ErrorException in Cpdf.php line 3855: Undefined index: at barryvdh/laravel-dompdf

Question

I am using laravel 5.2, The dompdf runs fine at localhost but when moved to AWS it keeps showing ErrorException in Cpdf.php line 3855: Undefined index:, in this

Answer 1

I faced this issue on the Linux machine. The error shown was

Undefined index: application/third_party/dompdf/lib/fonts\Times-Roman

If you observe the Directory separator before the font name '\' is not compatible in Linux environment. This path separator is hardcoded in the dompdf_font_family_cache.php file found in ../dompdf/lib/fonts folder.

Open the file in the editor and replace '\' with '/'. Save the changes. The code will start working.

Answer 2

Error solved by delete dompdf_font_family_cache.php file from storage/fonts and let the renderer regenerate the cache.
