Error: Platform 'golang' version '1.21.6' is unsupported

Bug Report

I created a new Static Web site in Azure, and linked it to my Azure DevOps repo to automatically build and publish. The pipeline, which is included below, was created and run, and it errored with "Error: Platform 'golang' version '1.21.6' is unsupported".

I have a Hugo static website setup, it builds and runs fine when using a local Hugo server on my machine.

AzureStaticWebApp_Log.txt

Start with the generated Azure DevOps pipeline and the attached AzureStaticWebApp_Log.txt, focusing on the AzureStaticWebApp@0 task and its reported Go 1.21.6 platform error. Reproduce with the basic Hugo site described in the issue; done means the generated pipeline builds and deploys the site successfully.
