Invalid JSON in response body, Node HTTP Request, Flow 2 course level 2

[igilfer1975]

When configuring the HTTP Request node for flow 2 of the level 2 course, I get no output, I get the error “Invalid JSON in response body”

It seems to be an error in the service of this URL: https://internal.users.n8n.cloud/webhook/level2-erp.

I have made the same configuration in Postman to validate if any parameter in the node was misspelled and in Postman I get a 200 OK response but the bodu is empty.

Can you help me with this problem?

I need to finish the course

I, too, am having this issue. Did you solve it @igilfer1975? I’m going to make my own post about it now
