Agent Throwing SystemError After Prompt

Posted on by ML-10031442-0 Microsoft Employee
I'm testing a new agent that I created for my team (CGE - Consumer Growth Engine).  On Day 1 when I tested, it worked great!  On Day 2, it won't run the results anymore after I use a prompt.  It's starts to process the results but as soon as it finishes processing, it shows the Error Message: 
 
Sorry, something went wrong. Error code: SystemError. Conversation ID: 66fc4e0f-c3b0-4c6c-82e2-2a220496a061. Time (UTC): 3/10/2025 2:37:15 PM.  
 
I'm looking to present this Agent to my team but need a working test.
 
Thank you.

    Have you checked if any setup has been modified recently such as topics, trigger phrases etc
     
    There might be some reasons:
    • If multiple topics have similar or overlapping trigger phrases, Copilot may not correctly resolve which topic to activate.
    • If the triggered topic includes an action (like calling Power Automate), a failure in those connectors can cause this error.
    • If the topic is storing or using variables that become invalid or exceed size limits, it may break unexpectedly.
     
    Ensure no two topics have similar or identical keyword triggers. If necessary, modify trigger phrases slightly for clarity. Disable the affected topic, save changes, then re-enable it. Temporarily disable Power Automate flows, API calls, or adaptive cards inside the topic. Run the test again to see if the error persists.


    Thanks.

    I'm using AI Builder prompts with Dataverse knowledge through the improve answer rate tool.
     
    All three prompts used to work fine, now they intermittently fail more often than not so I feel like this is something broken with Copilot Studio rather than my prompts. I really hope MSFT are monitoring these forums.
