Posted on by JG-12082124-0 4
Trying to attend the Copilot In a Day training and running into a blocker that is preventing me from successfully completing the training

https://learn.microsoft.com/en-us/training/modules/copilot-tools-online-workshop/prompt-tool
 
Step 13 - You're now ready to test this prompt tool in action, to do this, select the Test button.
When I click the test button, I get an error that says, "JSON.parse: unexpected character at line 1 column 1 of the JSON data"

I re-triggered the workflow at last 3-4 times, and also went directly through the Tools menu in Copilot Studio, but was unable to create a Custom Prompt.

Environment notes:
  • GCC tenant
  • Sandbox Environment running 2025 release wave 2 features
  • Pay-as-You-Go Azure subscription enabled

    Can you please share your actual work. I definitely appreciate the link but we can only help with yours specifically.
     
    You may even want to take a look at the flow in the background and see what is happening there, so we can see the input to your parse json
