Issue with Custom Connector PUT Call: “Data at the root level is invalid”

(0) ShareShare
ReportReport
Posted on by

Hey

 

I’ve encountered an issue with a custom connector I’ve created. The connector has multiple endpoints and various call types, all of which are functioning correctly except for the PUT call. When I test the PUT call, I receive the following error message:

“Data at the root level is invalid. Line 1, position 1.”

Interestingly, the same call works perfectly in Postman.

Here are the relevant configurations:

  • Endpoint: .../PurchaseOrder
  • HTTP Method: PUT
  • Body: { "No":"CD",      "ApproverEmail": "ch@gmail.com"}

Could you please help me identify the problem? Any insights or suggestions would be greatly appreciated.

Thank you in advance!
