NIFI Error o.a.nifi.processors.standard.InvokeHTTP

New Contributor
Hi, I'm having a NiFi error when I try to download a file. Especially in the InvokeHttp process. The error does not always appear for the uuid itself.

Any idea what would cause this exception, and how to fix it?

@Albert Mc Gregor

Have you tried pulling the same file from the command line of the NiFi system using wget?
