I am setting up a ticketing system with ADO as the backend. I am using Power Automate to read emails and create a ticket (work item in ADO). I have described the whole flow below. I am stuck at Flow 2. I get “Not found” response when I call the add comment Azure DevOps API “[/_apis/wit/workitems/17854?api-version=7.0](mailto:/_apis/wit/workitems/@%7boutputs(‘Create_new_PBI’)?%5b’body/id’%5d%7d/?api-version=7.0)”.

I appreciate any help you can provide to resolve this issue.

My Power Automate Flow

✅Flow1 – Create new ticket: If the subject has [SR], create a work item in Azure DevOps and save the attachment to the work item

✅a) Create a work item with the subject as title and body as the description

✅b) Save the attachment to Azure DevOps using post API

✅c) Relate the attachment to the newly created work item

❌Flow2 – Add comments to existing ticket: If the subject has [SR-XXXXX], add the email body as a comment. XXXXX stands for the work items id.

Flow 2 configuration:

Flow 2 raw input

Flow 3 output

404 – Not found

Appreciate your time and help ????

I have validated the url and the work item id. Everything seems to be correct based on the API reference below.
