Hi,

 

I am trying to create a new Service Connection, Method: POST and content-type as multipart/form-data.

But now when I drop the REST in an action chain, I get the below error. This is a show stopper for us. Please help urgently

1. {type: "abcs://proxy_auth_problem/ssl/cert", title: "SSL Certificate Error",…}
   1. detail: "A certificate in the remote path is reported as invalid because of 'Certificate chaining error'"
   2. status: 502
   3. title: "SSL Certificate Error"
   4. type: "abcs://proxy_auth_problem/ssl/cert"
