Mode not allowed in environment

What it means

This mode isn't allowed in this DROPSZ environment.

What to do

Read the status in the response. A 4xx status means the request was not accepted: check the request and what the message says, fix it and send it again. A 5xx status means the problem is on the DROPSZ side: try again after a moment, and contact support with the code if it keeps happening.
