Power Automate - AI Builder (Prompt) Issue: "Run a Prompt" action injecting item/source text

(0) ShareShare
ReportReport
Posted on by 2

We are facing an issue with a Cloud flow where we are using a Prompt to extract data off of PDF documents. the "Run a Prompt" action is injecting an extra parameter by itself and every run fails. This happens in new flows and existing ones; even the basic preconfigured prompts fail, so it’s not due to my custom mapping.

What gets added automatically:

Field shown in the action as item.item/source, value:

{"consumptionSource":"PowerAutomate","partnerSource":"AIBuilder",
"consumptionSourceVersion":"Flow",
"partnerSourceVersion":"28214da3-87df-433c-bc09-0be2065c2f01",
"displayName":"Cold-Mail-Outreach-Flow"}
 

In the code view / request payload this becomes a top-level parameter item/source, which OData rejects.

Error

400 Bad Request (0x80048d19)
The 
parameter 'item/source' in the request payload is not a valid parameter for the operation 'Predict'.
 

Please assist if you are aware of a fix for this issue!  We have tried the following without success:

- Logging out and back in

- Toggling between New Designer and Classic Designer Modes

- Rebuilding prompts from scratch.
