Azure
No function published after run the `publish` command
Problem
Hi, we are using the Azure function service for a new feature of our product. After testing the code locally using the func start command I tried to publish the code to the Azure function that I previously created in my resource group but it didn't work.
In order to avoid problems with my code I took the example code from the official Azure docu
After running the command func azure functionapp publish gpd2 I was expecting the same result as in the official docu (changing my domain name).

Functions in gpd2:

- Azure function runtime version:
4.15.1.1
Hi :) the problems seem related to the python library. We tried the same function using node and everything goes well.
Is there a solution for this? Running into the same problem on latest version 5085. It seems to me that there was a breaking change 2 weeks ago, since then I am unable to deploy to my azure functions
Edit: After downgrading to 5030 and switching to npm version instead of brew it seems to be working. Strange. Have the feeling that Tooling around Az-Fcts can be quite unreliable at times :/
Edit 2: Spoke to early. Functions that I saw were residue from previous Azure CLI deployment (which does not work, since it does not install the requirements.txt files :/ ). So back to square one, no Python Function Deployments possible.
Investigated this further. It seems like this is an issue with configuration, but cannot pin it down. For some azure functions it works for others it does not. Extremely flaky (main difference is created via ARM template vs created from portal). So I assume there is a difference in configuration somewhere. But was unable to find any (went through export templates, config, etc).
Is there any way to sanity check the configuration of an azure function? Over last half year have spent more time debugging azure functions than actually developing them :/
Okay, further investigated. It seems like that there is an internally used Environment Variable called Container_Name that is currently undocumented here. Once I remove it (or prefix it) the deployment goes fine.
@ Azure Team: It would be a great time saver to have an integrated sanity check for Azure Function that automatically checks for mismatching config, or config values that do not match the expected pattern, etc. Are there plans for something like that?
Facing the same issue with node function app
@felixnext where's this internally used Environment Variable? And how to remove it?
Haven't found the internal variable, but just prefixed all variables I used. Not even sure there is such an internal variable. Basically what I observed was:
- When I remove the variable (or prefix it, in this case CONTAINER_NAME -> FOO_CONTAINER_NAME) the issue went away
- When using the AZ CLI (instead of core-tools) I could deploy (but that requires you to build .python_package folder yourself, so not great)
That said, this issue can be caused by multiple other things (like not having properly set your AzureWebJobsStorage environment variable, or problems with your storage container). I created a UserVoice Item for a sanity check, so feel free to upvote that one as well: https://feedback.azure.com/d365community/idea/7eb1157e-50d0-ed11-a81b-00224850345d
For Node.js solved by following the steps below:
- Following guidance here - https://learn.microsoft.com/en-us/azure/azure-functions/functions-deployment-technologies#remote-build-on-linux added the following settings to func app configuration
ENABLE_ORYX_BUILD=true
SCM_DO_BUILD_DURING_DEPLOYMENT=true
- As per suggestion here - https://stackoverflow.com/a/75879560 need to add
"AzureWebJobsFeatureFlags": "EnableWorkerIndexing"
After adding these settings it started picking up the functions
Me too..any update? What is the right way to debug it? there is no relevant logs
Using linux python we face the same issue.
func azure functionapp publish
leads to
[Information] Loading functions metadata
[Information] Reading functions metadata
[Information] 1 functions found
[Information] 0 functions loaded
[Verbose] Request successfully matched the route with name '' and template 'admin/warmup'
and an empty functions list in the azure portal.
In my case I had to make sure that the function_app.py file runs successfully without any errors. For example, if there are imports in the file which might be failing, try moving them to a try except block and try again.
The whole issue exists because azure won't give us an log with correct error messages.
In my case it was caused by the missing pango library in the default container which is needed by an import. Creating my own docker image fixed it...
My python app (using V1 previously) started failing about a week ago. There seem to be various problems & solution so I'm trying to make my way through them, but it's very frustrating not to get any error messages when a deploy fails so I can't confirm which problem is mine.
In my case the problem was related to the wrong library in the python requirements.txt. I used psycopg instead of psycopg[binary]. Again, no deployment error or logs 🤒
