Failed to fetch Kudu App Settings. Internal Server Error (CODE: 500)

Type: Bug

Enter Task Name: Azure/functions-action@v1

Environment

• Server - Github actions

Issue Description

My app was working for months and I recently tried to update it and got this error.

I have searched the 'net high and low and have found similar errors, but nothing that matches this. None of the suggestions in those Issues/SO posts have helped. Examples:

Here’s my Action log:

My yaml:

    - name: 'Run Azure Functions Action'
      uses: Azure/functions-action@v1
      id: fa
      with:
        app-name: 'porscheoptioncodes'
        slot-name: 'production'
        package: '${{ env.AZURE_FUNCTIONAPP_PACKAGE_PATH }}/output'
        publish-profile: ${{ secrets.AZUREAPPSERVICE_PUBLISHPROFILE_xxx}}

My PublishSettings file which is stored in:

<publishData>
    <publishProfile profileName="PorscheOptionCodes - Web Deploy" 
       publishMethod="MSDeploy" 
       publishUrl="porscheoptioncodes.scm.azurewebsites.net:443" 
       msdeploySite="PorscheOptionCodes" 
       userName="$PorscheOptionCodes" 
       userPWD="<pwd>" 
       destinationAppUrl="http://porscheoptioncodes.azurewebsites.net" 
       SQLServerDBConnectionString="" 
       mySQLDBConnectionString="" 
       hostingProviderForumLink="" 
       controlPanelLink="http://windows.azure.com" 
       webSystem="WebSites">
       <databases />
    </publishProfile>
...
</publishData>

I went to the Azure Portal/Deployment Center and did Disconnect and reconnected, having it re-generate the workflow file.

After doing this, I found I had to change 'AZURE_FUNCTIONAPP_PACKAGE_PATHfrom.toApi` (because that’s what my client for this function expects).

So now my .yml is:

# Docs for the Azure Web Apps Deploy action: https://github.com/azure/functions-action
# More GitHub Actions for Azure: https://github.com/Azure/actions

name: Build and deploy dotnet core app to Azure Function App - PorscheOptionCodes

on:
  push:
    branches:
      - master
  workflow_dispatch:

env:
  AZURE_FUNCTIONAPP_PACKAGE_PATH: 'Api' # set this to the path to your web app project, defaults to the repository root
  DOTNET_VERSION: '3.1.301'  # set this to the dotnet version to use

jobs:
  build-and-deploy:
    runs-on: windows-latest
    steps:
    - name: 'Checkout GitHub Action'
      uses: actions/checkout@v2

    - name: Setup DotNet ${{ env.DOTNET_VERSION }} Environment
      uses: actions/setup-dotnet@v1
      with:
        dotnet-version: ${{ env.DOTNET_VERSION }}

    - name: 'Resolve Project Dependencies Using Dotnet'
      shell: pwsh
      run: |
        pushd './${{ env.AZURE_FUNCTIONAPP_PACKAGE_PATH }}'
        dotnet build --configuration Release --output ./output
        popd

    - name: 'Run Azure Functions Action'
      uses: Azure/functions-action@v1
      id: fa
      with:
        app-name: 'PorscheOptionCodes'
        slot-name: 'production'
        package: '${{ env.AZURE_FUNCTIONAPP_PACKAGE_PATH }}/output'
        publish-profile: ${{ secrets.AzureAppService_PublishProfile_xyz }}
  

The same error occurs.

I’m at my wits end. As I note this was working for months (last working commit was last September). Something changed between then on the Azure side that broke this, I believe.

Happy to be proven wrong, but I don’t know how to dive deeper to figure it out.

Same here, my deploy workflow was working 6 days ago and now it’s broken. I did not change anything on the workflow file or Azure

This is the error I’m seeing.

Eventually tracked out problem down to a mixture of the blob storage account not having table permission and not being public endpoint. If we have to swap to private endpoint, we’ll have to get a private build agent.
