Connection Builder Error: "undefined: There is no trace available for the connection"

Integration Builder Custom Connector giving error “undefined: There is no trace available for the connection”. I’m not sure where to begin troubleshooting this because there are no details about why this is occurring.

I see I’m getting a 404 error here, but when I use [baseURL]/changes?workspace_id=0 in postman, I do get a response. With a trace, I could identify why I’m encountering the 404 error. Without it, I don’t know what endpoint my request is going to.

Since you’re getting a 404 in the Integration Builder but a response in Postman, it might be worth checking the endpoint configuration in the connector. Double-check the URL and parameters to ensure they’re correctly set up.

Hi @debugger0732,

Looks like something got messed up while creating connection.

Kindly see below posts:

And below one is all about custom connector setup, should help you:

I had the same thought to doublecheck, but they do match as far as I can tell. My GETBYID/Get Record endpoint works properly. My GET/List Records endpoint doesn’t. As far as I can tell, I should be sending it to the same place as postman, but I can’t verify. I’m expecting “BASEURL/changes?workspace_id={workspaceid}” should send my request to “BASEURL/changes?workspace_id=0” when I input 0 as the value after clicking “Send Request”, but I can’t verify that’s where the query is going from UiPath because of the “undefined: There is no trace available for the connection” bug.

As far as I can tell, the connection is set up properly. My GETBYID/Get Record endpoint works properly, but my GET/List Records endpoint doesn’t.
