I'm getting an extremely weird error when trying to npm start my loopback application. I literally did nothing to the code and then this all of a sudden started to happen
Cannot start the application. TypeError: Cannot read property
'definition' of undefined
at getFieldsJsonSchemaFor (/Users/vikramkhemlani/Desktop/loopback/node_modules/#loopback/repository-json-schema/dist/filter-json-schema.js:101:64)
I have the same exact code in another file (which i actually created a git repo from using this repo) but this one is throwing this error for some reason
I went through the same issue.
Apparently there are caches which need to clean up before starting the application. (Expired caches also appear in openapi before I get into this issue)
The project needs to be clean and re-install packages by following:
npm run clean
npm install
I have the same problem.
However, I solved it when I tried the following.
delete node_modules directory.
npm install.

I am a student who has gotten a part time job embedded system programming. I am given a program the company uses, and asked to understand it. This is a working program. Therefore, the project can be built and flashed on ESP32 by the developers with no problem. So, the code and CMake files should have no issues. However, I cannot build the program either with VSCode extension nor with idf.py. In fact, I cannot build esp-idf examples from the official website, either.
Note: I am new to StackOverflow as well as to ESP32, so sorry if I made any mistakes here. If this post is problematic in any way, please inform me.
The error message from the terminal is shown here
I was initially using VSCode on Windows 10 (Windows is not activated). At first, ESP extension was completely failing to start the building process because it could not locate the tools. I was getting "could not be located" errors for all the tools. Below is a list of what I did in this setting:
I had v5.0.0 for esp-idf downloaded from Espressif server. I deleted it and tried v4.3.3 and then I tried to download from Github server. I downloaded the requirements for idf.py scripting environment and completed the settings for it as described by the Espressif's documentation.
I manually set the environment variables for IDF_PATH and PATH for both the user and for the system.
After 2, the initial error was gone. Unfortunately, I had a new error which indicated that ".elf" file for the project output could not be found. I do not exactly recall the error but if it is integral to the problem's solution I can try to replicate this issue.
I tried to delete and reinstall VSCode. I tried running VSCode with admin authority.
I tried changing the IDF_TOOLS_PATH in the VSCode esp-idf extension configurations from ".espressif" to "esp\esp-idf".
At this point, I moved to try to build the project on Ubuntu 22.04.1 LTS:
In Ubuntu, I got the fatal error: esp_event.h: No such file or directory error.
It does not seem to be a common issue and I could not find much about it online.
I followed the Linux setup steps in the documentation. It said that only step 1 (Downloading the prerequisites) was necessary for the VSCode extension.
I decided to try the "master branch" from esp-idf configurations as well. After I downloaded the master branch, the error changed to the current version: 'fatal error: esp_wifi.h: No such file or directory'
I also tried the idf.py in Ubuntu but I got the same error.
Both in Ubuntu and in Windows, the Doctor Command returns nothing. It does not even open the terminal or any window. I am not sure what it should return but some online discussions were asking about its return so I wanted to note it here.
Edit: When I tried the examples on Ubuntu, they actually build just fine. Doctor Command also works with examples.
However, the main code has still issues. Initially, I assumed I made some mistakes with esp-idf configurations. But, perhaps that was not the case.
I had the same problem and ended up editing my project's CMakeLists.txt. When I added "esp_wifi" to the "REQUIRES" list, it worked for me:
idf_component_register(
SRCS "main.c"
INCLUDE_DIRS res
EMBED_FILES res/settings.html
REQUIRES esp_wifi
)
I am using React Native and encountered the following error on my android emulator
I am new to React Native and was coding in App.js. I watched a tutorial online on how to use react-navigation so I was following it and created a homestack.js file. My app.js file was still working perfectly fine at this point.
I added code to homestack.js and then imported it to my app.js file but that's when this error popped up. This error was not resolved when I commented out all of the code on homestack.js nor when I commented out the import on my app.js file.
I followed the instructions on the error (clear watchman, delete node modules, yarn install, yarn reset cache) but this also did not resolve the issue.
The fix:
Since none of the above fixed the issue, I removed the homestack.js file from my root folder completely which then fixed the issue. What I did not expect however was that when I put the homestack.js file back into the root folder to see what would happen, the app ran again fine with no issues. It was as if the error never happened.
I guess my question is, what was the actual issue here? Why did taking the file out of the folder and then placing it back in fix the issue? I ran 'npx react-native run-android' after every step of the above fix process so the issue was not because the emulator was running an old version.
Following this error, You have imported react-navigation-stack without install the package. You can install the packge
yarn add react-navigation-stack #react-native-community/masked-view react-native-safe-area-context
or
npm install react-navigation-stack #react-native-community/masked-view react-native-safe-area-context
To know more https://www.npmjs.com/package/react-navigation-stack
After install the package clean project by executing command cd android && gradlew clean, then debug your project.
I am trying to figure out how to package an unchanged fork of VS Code.
My first steps were to follow the electron application distubution documentation, which has not been successful. I also found this post, where another user had the same question. However, the vscode-win32 gulp task seems to have been replaced by x64 and ia32 versions, and when I try running these tasks they generate an out-vscode folder as opposed to a full electron project.
This led me to believe that I can use this new out folder (as well as node modules, packages.json, etc.) with the electron release being used by VS Code to mimic the resources/app folder from the installed version of VS Code in Program Files, however when I try running electron.exe using this method I get:
The factory method of "vs/code/electron-main/main" has thrown an exception TypeError: Path must be a string. Received undefined
In short, I have been struggling with this for a couple of days, and I am out of ideas. If anyone has packaged the project and can offer a suggestion for how to do so, I would really appreciate it.
SOLVED
The issue seemed to be due to being branched off of master as opposed to release. I'd assume there are changes in main that aren't accounted for in the gulp task.
For anyone confused by my post, the expected behavior for a successful build is for a folder named VSCode-win32-x64 to be generated in the directory where your vscode clone is located.
I keep getting this error in my output when trying to package iOS through Ionic cloud "Error: Registry returned 404 for GET on https://registry.npmjs.org/[MyAppName]". I've followed a few other forum posts that I could find to no avail. Any help would be much appreciated!
in package.json you have [MyAppName] as package or something like that, which when trying to fetch from npmjs.com its not there since you havent publish it, post package.json to check it.
I was using [MyAppName] as a placeholder for my physical app name; for the post. The issue turned out to be the Cordova plugins directory.
To resolve I ran:
ionic state clear --plugins
This, however, resulted in only partial removal of the plugins. I further had to manually delete the rest. Finally I ran:
ionic state restore --plugins
I can build successfully now.
I'm using W7 64 bi , and just got an error from the github client app. It says:
failed to sync branch. you might need to open a shell and debug the state of this repo.
What do I do now ?
I know this will sound crazy, but try restarting your computer.
This happend to me yesterday; I was getting this error, and upon checking: \AppData\Local\GitHub\TheLog.txt
I found messages like:
AppData\Local\GitHub\PortableGit_ca477551eeb4aea0e4ae9fcd3358bd96720bb5c8\bin\sh.exe:
*** Couldn't reserve space for cygwin's heap, Win32 error 0
The problem comes around to GitHub for Windows updating itself (in particular the cygwin-ized PortableGit) in the background while I was using it. Ultimately, some cygwin dlls from the previous PortableGit dlls were still loaded in memory causing errors when trying to execute the new (updated) PortableGit commands.
Restarting cleared out all the previously loaded cygwin dlls.
You might have a more complex problem than my answer can solve, but -- for anyone else who comes across this question -- some basic solutions can be found in this video. In short, status.github.com, git status, and gitstatus are your friends. See what they tell you and then continue your sleuthing with that new information in mind. You can use these tools using Git Shell that comes with the Github Windows client.
I'll note that my own problem stemmed from trying to sync a file that was too large: I only found this by using the Git Shell, which gave me the error when I tried git sync. I'm currently looking for ways to remove the file in question in previous commits so I can sync my repo appropriately. The guide I am currently following can be found here, and if it seems to be taking me in the right direction (it was actually recommended in the Git Shell error message!)
I had this error before, and I fixed it by reinserting the credentials for my github account. Turns out that github logged me out for some reason
