Azure Static Web App began getting a server error due to Python 3.6 not being supported in WebJobs.Script.Workers

I published a next.js website as an azure static web app and it was working fine. Recently I have been getting a Server Error: There was an unexpected error in the request processing when trying to access the site. I am not exactly sure which commit started this because the Github actions have been working. Application insights gives me the following error: There was an unexpected error in the request processing. Exception Properties || || |Event time|4/25/2023, 9:55:26.2197906 AM (Local time)|| |Message|Version 3.6 is not supported for language python|| |Exception type|System.NotSupportedException|| |Failed method|Microsoft.Azure.WebJobs.Script.Workers.Rpc.RpcWorkerDescription.ValidateRuntimeVersion|| |Problem Id|System.NotSupportedException at Microsoft.Azure.WebJobs.Script.Workers.Rpc.RpcWorkerDescription.ValidateRuntimeVersion|| |Assembly|Microsoft.Azure.WebJobs.Script, Version=4.17.0.0, Culture=neutral, PublicKeyToken=null| Call Stack

I don't use any azure functions from the site, I call an azure function for to send emails from the contact form, I don't use python either.... So if anyone has any clues to solving this I would be very grateful, I am considering moving the site to vercel.

@Ben Roberts Thank you for reaching out to Microsoft Q&A, apologize for the inconvenience caused on this.

Looking at the error message shared it would be very hard to understand what the reason might be you were landed up in this issue.

Could you please check and help me with more information on the below:

Have you added any API to your static webapp? If yes, can you check which language does API uses?

If the API is using Python 3.6 then I would suggest you upgrade the python latest versions(>3,6) and check since python 3.6 is EOF life on Azure.

If you don't have any api added to the static webapp and if you are still facing the issue do help us with the static webapp name, last four digits of your subscription id, issue start time (in UTC) to check and assist your further on this.
