Sometimes In Production | Livewire JSON parse error: Unexpected non-whitespace character at position
Environment:
- Laravel 12 + Filament v3
- Production server
Issue:
Intermittent JavaScript errors occur when performing any action that uses JS in the admin panel (e.g., login attempts). The error appears randomly and makes the functionality unusable. Restarting the Docker container temporarily fixes the issue.
Error Details:
Uncaught (in promise) SyntaxError: Unexpected non-whitespace character after JSON at position 2408
at JSON.parse (...)
at sendRequest (livewire.js:4340)
at async RequestPool.send (livewire.js:4060)
