Function language detection error leads to deploy failure

[Cypher1]

Describe the bug

Static web app (Vite/VueJs) + Azure functions deployment fails with error (presumably from Oryx)

Error:

The function language detected is unsupported or invalid. The following languages are valid: dotnet, dotnetisolated, node, python. If you are not using Azure Functions, you can skip this check by removing the 'api_location' input from the workflow file.

A clear and concise description of what the bug is.

To Reproduce Steps to reproduce the behavior:

1. Create a static web app using VueJs
2. Add a Azure cloud function
3. Generate the workflow file
4. Upload to github actions
5. See error in deploy log

• Our GitHub Actions or Azure Pipelines workflow YAML file

Expected behavior App should deploy with functions alongside (this previously worked, even this morning).

Note: The repository is private but I'm happy to assist by providing logs and attempting changes.

We found a work around / awkward solution.

Setting the apiRuntime in staticwebapp.config.json is necessary, even though Oryx correctly detected the api language, and even built the code (and previous deploys worked...)

Not sure how this is possible but we have a path forward. Best of luck to anyone who finds this, it looks like Azure don't follow this issues page much.
