I'm new in Laravel, I use laravel 5.2 and I'm trying to generate a report using DomPdf but I'm getting error:

ErrorException in class.pdf.php line 3154

Undefined index:

  • This is probably due to an issue parsing the font for the metrics. I think an update to php-font-lib could help, but there are still some issues that need to be worked out. Have you tried dompdf 0.7.0 or another font? – BrianS Jun 13 '16 at 19:37
  • FYI, this is actually just a warning which does not require halting execution. Laravel is greedy with exceptions, but you *could* prevent this from halting execution by telling Laravel to ignore these errors (see [this answer](http://stackoverflow.com/a/18499557/264628)). I don't know enough about Laravel to stop it from halting on PHP notices/warning just for PDF rendering. – BrianS Jun 13 '16 at 19:39

I was having this same problem, and I found a solution that makes no sense to me.

The HTML I was passing to dompdf didn't have any line breaks, like:

<html><body>content here<body></html>

Adding a break after the body tag fixed the problem.

<html><body>
content here
</body></html>

No clue what's going on, but now it works. Hope this fixes your problem too.
