Unable to Process API Response in Microsoft Copilot

(0) ShareShare
ReportReport
Posted on by
 

I am experiencing an issue where Microsoft Copilot is unable to process or convert the API response correctly when a custom action is triggered. Below are the details:

Steps Taken:

1.Created a custom Power App that calls my API.

2.Built a custom connector for the API and integrated it as an action in Microsoft Copilot Builder.

3.When a question is asked, the action is invoked successfully, the API is triggered, and the response is generated correctly at the API end.

Observed Behavior:

•While the API is returning the expected response, Copilot is unable to process it properly.

•An error message is displayed with the following details:

Sorry, something went wrong. Error code: SystemError. 
Conversation ID: a1eb1cc4-0c90-442b-803a-c2bc94ae7821. 
Time (UTC): 12/3/2024 1:38:53 PM.

Additional Information:

•This issue started occurring after today, 12/3/2024, at 9:30 AM IST.

•Prior to this, the setup was functioning as expected, and responses were processed without any issues.

Request for Support:

I suspect something might be wrong on Copilot’s end, as the API and custom actions are functioning correctly. Could you please help investigate this issue?

Any guidance or assistance to resolve this would be greatly appreciated.

    Hello,
     
    there were some problems with custom connectors in Copilot Studio last time. I guess we just need to wait for it to be stable, I wouldn't recommend using custom connector as a separate agent action. What you could do as a workaround is to use a flow with custom connector action. 
     
    In case of any other questions, let me know. If the answer helped you, mark it, so that others can benefit from it.
     
    Best regards,
