Describe the problem/error/question

when i create a mcp server trigger, I’ve switched to take active. I copy production URL. Used in the tool of ai agent.
I got the following prompt：

Failed to execute tool “linkedin_data_hunter”

Error: [ { “code”: “invalid_type”, “expected”: “object”, “received”: “undefined”, “path”: , “message”: “Required” } ]

What is the error message (if any)?

Failed to execute tool “linkedin_data_hunter”

Error: [ { “code”: “invalid_type”, “expected”: “object”, “received”: “undefined”, “path”: , “message”: “Required” } ]

Please share your workflow

Hi @laughing_laughing

I noticed a couple of issues

According to fdocs docs You’re using a GET request instead of POST for /search-posts end point, and it looks like you’re not sending any request body as well.

Please follow this example that includes an example of the body and edit it to suit your needs.

Please double-check the endpoint you’re using,it might help to review their documentation…
