Jupyter extension jupyter_scheduler fail to create job - jupyter

After installing the Jupyter extension jupyter_scheduler (1.2.0) with pip on my JupyterHub server following the docs, it is impossible to create a schedule for a notebook.
On creation of a job it shows the message "Unexpected error occurred during creation of job."
Error during job creation
I verified that both the jupyter_scheduler server extension and the #jupyterlab/scheduler prebuilt lab extension are indeed enabled. No error message is shown and all looks OK to me.
Any idea how to find more info about the "Unexpected error" in log files or elsewhere is more than welcome.

How to solve oracle connector error in DataStage?

I am facing a sudden issue in my datastage job. when run the job it eventually aborts/fails and gives below error. whereas this was not happening earlier, I ran the job multiple times and it completed successfully.I have not made any changes.
I am getting this error in my source oracle connector.
following is the error:
Oracle_Connector: The connector could not access the oracle server using the specified Username.
Method: OCISessionBegin:OCI_CRED_RDBMS,
Error code:28040, Error message ORA-00000: normal,
successful completion.(CC_OraConnection::verifyConnection, file CC_OraConnection.cpp, line 5,171)
The most probable cause is that the password of the Oracle user has expired.

deleting and purging from keyvault using the azure cli capturing error messages

Im using AzureCLI#2 in devops to execute (via powershell) cli commands to first delete and then purge.
If you delete a cert from the keyvault you cannot purge it until it is fully deleted.
The error handling is wierd with the CLI (you cant use try/catch (See https://rajbos.github.io/blog/2019/07/12/Azure-CLI-PowerShell)
An error messsage is produced when the item is still deleting and ALSO when the item has been purged.
I need to know the difference between these two scenarios. Any idea how I can actually get the error message?
If the azure cli command failed, you can find the error message on the log of task AzureCLI#2. Through it isnot output to the error stream in the task log. See below screenshot.
You can set the attribute failOnStandardError to true. And the errors will be output to the error stream in the log.
As the blog you mentioned pointed out try/catch is not working with azure cli, since azure cli commands are not designed for Powershell. You can also write to the error stream an error message just to indicate where the actual error message resides in the log: See below:
$output = az keyvault key delete --name keyName --vault-name ..
if(!$output){
Write-Host "[Error] Error in deleting key keyName"
}

NuGet gives me an error when accessing server

We have set up a small NuGet server in our corporate network. It works fine for EVRYONE except me ;-)
When I try to list the available packages in Visual Studio, all I get is this error message:
Unable to load the service index for source (...).
An error occurre while sending the request.
The remote server returned an error: (502) Bad Gateway.
I've been struggeling with this issue for hours without success. Can anyone give me a hint on why this error occurs?

Running conda command in command line

I am trying to install the MLxtend library for python. The command to do this should be simply typing:
conda install mlxtend --channel conda-forge.
I tried running it in the command prompt right when it opened up (which was C:\Users\Ben. When this didn't work, I changed directories to C:\anaconda\anaconda3\scripts and ran the same command there. It again didn't work so I tried to update anaconda by running: conda update conda. This again didn't work and I am not sure exactly what is going on that is causing the error. Everything on Google and everywhere else hasn't worked so I'm hoping y'all know how to fix this.
Error I'm getting:
