Laravel cannot find the class <class>

What it means

A route or binding points to <class>, which does not exist: a wrong namespace or file name case (Linux is case sensitive), or old route syntax «Controller@method» without the namespace.

The build passed, but the app did not start or did not answer the health check.

Typical causes

• The app does not listen on 0.0.0.0 and the port from the PORT variable
• An environment variable is missing, or the database or Redis is not connected
• The start command is wrong or the process exits right away

How to fix it on mevcore

Use the array syntax with the controller class and run composer dump-autoload locally.

1. 1 Open the app in the mevcore panel: the Problems card on the overview shows this error and the log line it was found in.
2. 2 After the fix, deploy again. If it fails again, the log ends with [mevcore] lines naming the new error code.
3. 3 The "Ask AI" button next to the error prepares a request for ChatGPT or Claude: the error code, the end of the log without secrets and the app settings.

For an AI assistant

The same in English: paste it together with the log into the AI chat.
