launch.json for azure core function version 3 - azure

Question

I was working in the azure core tools version 2 and recently updated to version 3. Now I am not able to run any functions as it is showing error message "connect Econnrefused 127.0.0.1:9091".
Here is my launch.json
{
"version": "0.2.0",
"configurations": [
{
"name": "Attach to Python Functions",
"type": "python",
"request": "attach",
"port": 9091,
"preLaunchTask": "func: host start"
}
]
}
I am working on windows machine and using 1.6.1 azure functions versions.
Do I have to change something? I checked and this is common error and reinstalling the extensions should work?I tried all those. Do you think, I am missing anything ?

Answer 1

Please check if the below workarounds help to:
Approach 1:
Use Integrated terminal in the VS Code and then run the Azure Functions Python:
I will also get this issue most of the time and My working launch.json configuration will be like this:
{
"version": "0.2.0",
"configurations": [
{
"name": "Python: Current file",
"type": "python",
"request": "launch",
"program": "${file}",
"console": "integratedTerminal"
},
{
"name": "Azure Functions",
"type": "python",
"request": "attach",
"port": 9091,
"preLaunchTask": "func: host start"
}
]
}
Approach 2:
If the above approach gets the issue still, then try changing the port number and then run the Azure Functions Python.
Approach 3:
Instead of running the Azure Functions Python from the VS Code built-in Run Menu, try with the commands func host start in the integrated terminal like:
If that does not help you, please refer to this workaround given here which solves the specific error of Azure Function Python - Error Connection Refused.
