From time to time we receive error reports from customers for one of our gadgets about “Bad request - 400” error with the stack trace “Request header is too large”.
The gadget sends POST requests to get the data from Server and it is the custom REST API endpoint implemented in the app.
The problem definitely exists, but I don’t understand even how to reproduce it in order to fix.
Maybe anyone faced a similar issue in the past? I’d appreciate any suggestions on how to investigate such a problem.
