Portainer Error 500 Revealer Autor: newchel

Detailed Description
Tired of scratching your head when Portainer throws a generic "Failure - Request failed with status code 500" during a complex stack deployment?
According to official documentation, figuring out why a deploy failed requires opening your browser Developer Tools, replicating the crash, identifying the failed network request, and manually parsing JSON payloads.

Portainer 500 Error Revealer automates this entire manual workflow instantly.
By silently monitoring frontend network requests, this hyper-lightweight tool catches 500 error responses mid-flight, parses the specific failure reason generated by the Docker engine, and drops a clean, auto-fading overlay directly on your screen so you can debug what went wrong fast.
