Hello,

I found the following two posts describing an issue the I currently have.

https://powerusers.microsoft.com/t5/Connecting-To-Data/SharePoint-Online-sometifclennertmes-returns-...

https://powerusers.microsoft.com/t5/General-Power-Automate/BUG-Send-HTTP-Request-to-Sharepoint/td-p/...

My flow calls the SharePoint webservice URI GET /_api/web/lists/GetByTitle('ListTitle')/Items(12080)/Versions

Recently this began to fail some times reporting a 400 Bad request, but with the request message that it ran into 503 Service unavailable.

The problem with this is that Power Automate will automatically retry on a HTTP 503 error, but does not retry on a HTTP 400 error.

So now my flow will fail in stead of retry. Please look into this and align the HTTP status code with the actual error.

I also posted this problem on the Power Automate forum with a screenshot. https://powerusers.microsoft.com/t5/I-Found-A-Bug/SharePoint-HTTP-error-503-returns-as-HTTP-400/m-p/559801#M7055
