I am trying deploying my flask application to the Bluemix where it is configured by Bluemix Python Flask BuildPack and it is not a custom build back.
#app.route('/run', methods=['GET','POST'])
def stockModuleRunner():
stockCode = request.args.get("stock_code","")
# Store the reference, in case you want to show things again in standard output
old_stdout = sys.stdout
# This variable will store everything that is sent to the standard output
result = StringIO()
sys.stdout = result
# Here we can call anything
# Here we can call anything we like, like external modules, and everything that they will send to standard output will be stored on "result"
r = Resilience.Resilience()
r.main(stockCode)
# Redirect again the std output to screen
sys.stdout = old_stdout
# Then, get the stdout like a string and process it!
result_string = result.getvalue()
print(result_string)
#r = Resilience.Resilience()
#r.main(stockCode)
resp = Response("<html><pre>"+result_string+"</pre></html>")
resp.headers['content-type'] = 'text/html; charset=utf-8'
return
I set the content type of my response as a text/html. But it didn't work in the Bluemix, while it worked in my local environment. In the Bluemix, it changed to text/xml automatically. I confirmed it through the network tab of chrome developer tool. I got the error like the followings. As per the result of a google search, I found out that it is a sort of xml parsing error. Do you have any idea of this problem?
This page contains the following errors:

Trying to use google logging client library for writing logs into gcloud, specifically, i'm interested in writing logs that will be attached to a managed resource, in this case, a Vertex AI endpoint:
Code sample:
import logging
from google.api_core.client_options import ClientOptions
import google.cloud.logging_v2 as logging_v2
from google.oauth2 import service_account
def init_module_logger(module_name: str) -> logging.Logger:
module_logger = logging.getLogger(module_name)
module_logger.setLevel(settings.LOG_LEVEL)
credentials= service_account.Credentials.from_service_account_info(json.loads(SA_KEY_JSON))
client = logging_v2.client.Client(
credentials=credentials,
client_options=ClientOptions(api_endpoint="us-east1-aiplatform.googleapis.com"),
)
handler = client.get_default_handler(
resource=Resource(
type="aiplatform.googleapis.com/Endpoint",
labels={"endpoint_id": "ENDPOINT_NUMBER_ID",
"location": "us-east1"},
)
)
#Assume we have the formatter
handler.setFormatter(ENRICHED_FORMATTER)
module_logger.addHandler(handler)
return module_logger
logger = init_module_logger(__name__)
logger.info("This Fails with 501")
And i am getting:
google.api_core.exceptions.MethodNotImplemented: 501 The GRPC target
is not implemented on the server, host:
us-east1-aiplatform.googleapis.com, method:
/google.logging.v2.LoggingServiceV2/WriteLogEntries. Sent all pending
logs.
I thought we need to enable api and was told it's enabled, and that we have: https://www.googleapis.com/auth/logging.write
what could be causing the error?
As mentioned by #DazWilkin in the comment, the error is because the API endpoint us-east1-aiplatform.googleapis.com does not have a method called WriteLogEntries.
The above endpoint is used to send requests to Vertex AI services and not to Cloud Logging. The API endpoint to be used is the logging.googleapis.com as shown in the entries.write method. Refer to this documentation for more info.
The ClientOptions() function should have logging.googleapis.com as the api_endpoint parameter. If the client_options parameter is not specified, logging.googleapis.com is used by default.
After changing the api_endpoint parameter, I was able to successfully write the log entries. The ClientOptions() is as follows:
client = logging_v2.client.Client(
credentials=credentials,
client_options=ClientOptions(api_endpoint="logging.googleapis.com"),
)
I run a flask server in which this function is called whenever an specific action occurs on the page :
def generate_audio(text, target):
# create the path
tmp_dir = os.path.join(os.getcwd(), "app/data/audio")
if not os.path.exists(tmp_dir):
os.mkdir(tmp_dir)
path = os.path.join(tmp_dir, f'{target}-{text}.wav')
# query the API
speech_config = SpeechConfig(
subscription=cfg['speech']['key'], region=cfg['speech']['location'])
audio_config = AudioOutputConfig(filename=path)
synthesizer = SpeechSynthesizer(
speech_config=speech_config, audio_config=audio_config)
synthesizer.speak_text("A simple test")
At the end of the execution, the file containing the audio is just an empty 0B file. I literally copy pasted the quick start guide, so I do not know what is wrong.
What I did try is to change the subscription key to something random and no error was raised. In the logs from the azure service webpage nothing comes up either.
Here's the cancellation details
SpeechSynthesisCancellationDetails(reason=CancellationReason.Error, error_details="Connection failed (no connection to the remote host). Internal error: 11. Error details: Code: 0. USP state: 2. Received audio size: 0 bytes.")
Here's the log
https://pastebin.com/aapsMXYc
I was also facing the same issue and found that I was entering incorrect location name. E.g. in resource, you will see a location name like Central India but in SDK it should be entered as centralindia (this name I found under key management). Hope this will help in resolving this issue.
Thanks
I am trying to download a file for the first time from Google Cloud Storage.
I set the path to the googstruct.json service account key file that I downloaded from https://cloud.google.com/storage/docs/reference/libraries#client-libraries-usage-python
Do need to set the authorization to Google Cloud outside the code somehow? Or is there a better "How to use Google Cloud Storage" then the one on the google site?
It seems like I am passing the wrong type to the storage_client = storage.Client()
the exception string is below.
Exception has occurred: google.auth.exceptions.DefaultCredentialsError
The file C:\Users\Cary\Documents\Programming\Python\QGIS\GoogleCloud\googstruct.json does not have a valid type.
Type is None, expected one of ('authorized_user', 'service_account').
MY PYTHON 3.7 CODE
from google.cloud import storage
import os
os.environ["GOOGLE_APPLICATION_CREDENTIALS"]="C:\\GoogleCloud\\googstruct.json"
# Instantiates a client
storage_client = storage.Client()
bucket_name = 'structure_ssi'
destination_file_name = "C:\\Users\\18809_PIPEM.shp"
source_blob_name = '18809_PIPEM.shp'
download_blob(bucket_name, source_blob_name, destination_file_name)
def download_blob(bucket_name, source_blob_name, destination_file_name):
"""Downloads a blob from the bucket."""
storage_client = storage.Client()
bucket = storage_client.get_bucket(bucket_name)
blob = bucket.blob(source_blob_name)
blob.download_to_filename(destination_file_name)
print('Blob {} downloaded to {}.'.format(
source_blob_name,
destination_file_name
)
)
I did look at this but I cannot tell if this is my issue. I have tried both.
('Unexpected credentials type', None, 'Expected', 'service_account') with oauth2client (Python)
This error means that the Json Service Account Credentials that you are trying to use C:\\GoogleCloud\\googstruct.json are corrupt or the wrong type.
The first (or second) line in the file googstruct.json should be "type": "service_account".
Another few items to improve your code:
You do not need to use \\, just use / to make your code easier
and cleaner to read.
Load your credentials directly and do not modify environment
variables:
storage_client = storage.Client.from_service_account_json('C:/GoogleCloud/googstruct.json')
Wrap API calls in try / except. Stack traces do not impress customers. It is better to have clear, simple, easy to read error messages.
When using the Python Eve Database hooks I am trying to modify the request parameters on a post call I am getting the below error
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<title>500 Internal Server Error</title>
<h1>
Internal Server Error
</h1>
<p>The server encountered an internal error and was unable to complete your
request.Either the server is overloaded or there is an error in the
application.
</p>
And when I remove the code fragment to modify the Request Parameters the resource is created successfully.
Please find the code snippet as :-
__author__ = 'sappal'
from eve import Eve
import time
def insert_people(items):
# retrieve request parameter, if present
print items['userid']
print items['email']
items['userid']= "Tushar_Sappal" + str(int(time.time()))
items['email'] = "sappal.tushar"+str(int(time.time()))+"#gmail.com"
print items
# Creating the instance of the EVE Application
app = Eve()
app.on_insert_people += insert_people
if __name__== '__main__':
app.run(host='0.0.0.0')
items is a list so you should update your code like this:
def insert_people(items):
for item in items:
item['userid']= "Tushar_Sappal" + str(int(time.time()))
item['email'] = "sappal.tushar"+str(int(time.time()))+"#gmail.com"
While in development, you usually want to run your application in debug mode, so you can get a full stack-trace with the error:
app.run(debug=True)
Just make sure to disable the debug mode when running in production.
I am using the FB cookie and trying to decode it into json, the code looks similar to this
def value = cookie.value
String[] tokens = value.split('\\.')
String decodeToken = new String(Base64.decodeBase64(tokens[1].getBytes()),
'UTF-8')
def jsonValue = JSON.parse(decodeToken)
Where the cookie is the one that facebook creates when using the login plugin.
Now, when I run this using run-app, there are no issues. However, when running it using run-war, an exception is thrown when the JSON parser tries to create the JSON object from the String.
Caused by: org.codehaus.groovy.grails.web.json.JSONException: Expected a ',' or '}' at character 304 of {"algorithm":"HMAC-SHA256","code":"AQCvjV......."user_id":...50089"\00\00
Debugging it further, it seems the String that gets created from the decode call, is fine when run in the context of run-app. But when run-war is done, the last character of the String is not a '}' but some garbled character - and this is the one that causes the parser to throw an exception.
What could be a cause of this? What would be a good point to start debugging this further?
I have even tried to invoke getBytes() by using a specific encoding - but to no avail.
run-app runs a grails applications and allows the reloading from resources
run-war generates a war file and runs the war file, so no reloading of resources.
you could manually do grails war and then run it on a local instance of tomcat.
