Azure Function Deployment Failed: `Malformed SCM_RUN_FROM_PACKAGE when uploading built content.`

Question

Trying to deploy a python-runtime (v3.6.9) Azure function using the VS Code Azure Functions extension.

I created the function just fine, then...

1. Clicked Upload from the extension
2. Create new function app in Azure (advanced)
3. Entered a globally unique function name
4. Selected Python 3.6 as runtime
5. Selected Consumption hosting plan
6. Selected an existing resource group (created just for this project)
7. Selected an existing storage account (created just for this project)
8. Selected Skip for now for App Insights
9. Output window shows "creating new function app"

...but the process errors out with:

I also tried...

• Right click on Function project
• Deploy to Azure

...same outcome.

EDIT1: Also tried performing a remote build from the cli per @hury-shen's recommendations:

(.venv) user@system:~/Documents/azureBlobToS3$ func azure functionapp publish azureblobtoawss3 --build remote

Getting site publishing info...
Remote build is a new feature added to function apps.
Your function app azureblobtoawss3 does not support remote build as it was created before August 1st, 2019.
Please use '--build local' or '--build-native-deps'.
For more information, please visit https://aka.ms/remotebuild

I then proceeded to update the application using az functionapp update -g <RESOURCE_GROUP_NAME> -n <APP_NAME>. Same result.

I also added the Application Settings listed here to enable remote build on Linux. Same result.

I then tried running func azure functionapp publish <APP_NAME> --build local instead and get the error:

There was an error restoring dependencies.   Could not find a version that satisfies the requirement pkg-resources (from -r /home/user/Documents/azureBlobToS3/requirements.txt (line 19)) (from versions: )
No matching distribution found for pkg-resources (from -r /home/user/Documents/azureBlobToS3/requirements.txt (line 19))

Yet pip shows the pkg-resources dependency being met!

(.venv) user@system:~/Documents/azureBlobToS3$ pip install pkg-resources

Requirement already satisfied: pkg-resources in ./.venv/lib/python3.6/site-packages

EDIT2: Removed pkg-resources from requirements.txt just to test

I'm stuck in a loop here. Unable to build remote, unable to build locally.

There was an error restoring dependencies. ERROR: cannot install cryptography-2.9.2 dependency: binary dependencies without wheels are not supported when building locally. Use the "--build remote" option to build dependencies on the Azure Functions build server, or "--build-native-deps" option to automatically build and configure the dependencies using a Docker container. More information at https://aka.ms/func-python-publish

Has anyone else see this error? How do I troubleshoot?

Answer 1

Deploy the python function by extension often occurs some problem, so I suggest you to use command to deploy the python function from local to azure. Please refer to the steps below:

1. Go to azure portal and create a function app(python).

2. Click "Terminal" button in your VS code to open the "TERMINAL" window and run the command below to generate the "requirements.txt" which includes all of the modules installed in your function.

pip freeze > requirements.txt

3. Deploy the function from local to azure by running the command below:

func azure functionapp publish <functionAppName> --build remote

The <functionAppName> is the name of the function app which you created just now. After running this command, the function code will be deployed from local to azure and azure will install the modules by the content of the "requirements.txt" which we generated above.

Hope it helps~

Answer 2

I encountered these exact same errors including the edits and followed all recommended steps to resolve. My issue was in VSCode, I was building with with Python 3.7 even though 3.6 was installed. Uninstalling Python 3.7 and forcing 3.6 build resolved my issue.

Answer 3

In my case, it was because the Function App couldn't access the Storage Account. I modified the connection strings stored in the AzureWebJobsStorage & AZURE_STORAGE_CONNECTION_STRING appSettings.

To determine this, I built the function app locally and tried to deploy.

func azure functionapp publish func-durableFuncAci-ussc-demo --build local --build-native-deps

I got the following error, which told me there was an error in the configuration of the Function App.

Error creating a Blob container reference. Please make sure your connection string in "AzureWebJobsStorage" is valid

Answer 4

Creating and Deploying FunctionApp from VS Code works, VS code will have issues with deploying functions which are created from portal.
