required parameter $dompdf follows optional parameter $paper - barryvdh/laravel-dompdf

Question

I am trying to render pdf file with dompdf, but I got this issue:

required parameter $dompdf follows optional parameter $paper

image - required parameter $dompdf follows optional parameter $paper

Answer 1

It probably happens because you are using php 8, and your current laravel dompdf doesn't support new changes of php 8.

To fix it try to use this line in your composer dependency:

"barryvdh/laravel-dompdf": "^0.9.0"

and run:

composer update

For more details see:

And you can see what happens in php-8 with function parameters in this issue:

Required parameter $xxx follows optional parameter $yyy
