AssemblyInfoFilename file not found

When I try to update the AssemblyInfo.cs files by setting the updateAssemblyInfo: true I get the following error:

 AssemblyInfoFilename file not found at 

Might be related to this issue on the GitVersion repo.

You can view the error in action at:

To reproduce:

1. Create a GitHub workflow file with the following:

name: CI
on: [push]

jobs:
  build:
    name: Build Job
    runs-on: macos-latest
    defaults:
      run:
        working-directory: Source

    steps:
      - name: Checkout
        uses: actions/checkout@v2

      - name: Fetch history for GitVersion
        run: git fetch --prune --unshallow

      - name: Install GitVersion
        uses: gittools/actions/gitversion/setup@v0.9.3
        with:
          versionSpec: '5.3.4'

      - name: Generate Version Info using GitVersion
        id: gitversion
        uses: gittools/actions/gitversion/execute@v0.9.3
        with: 
          updateAssemblyInfo: true
      
      - name: Display GitVersion values
        run: |
          echo "Major: ${{ steps.gitversion.outputs.major }}"
          echo "Minor: ${{ steps.gitversion.outputs.minor }}"
          echo "Patch: ${{ steps.gitversion.outputs.patch }}"

1. When run the following error message is displayed:

Run gittools/actions/gitversion/execute@v0.9.3
  with:
    updateAssemblyInfo: true
    useConfigFile: false
  env:
    DOTNET_CLI_TELEMETRY_OPTOUT: 1

I’ve submitted a PR (see #316 ) to resolve this issue.

A temporary workaround for this is to specify /updateAssemblyInfo in the Additional GitVersion arguments parameter of the Azure Devops Task. (Huge thanks for this tip on another issue https://github.com/GitTools/GitVersion/issues/2225#issuecomment-624425847)
