Invoice Design - 500 Internal Server Error

Self-Hosted | v5
1

I just finished a fresh installation (V5.3.55) today on Ubuntu 20.04.3. However, I’m having a problem with “500 Internal Server Error” whenever I try to access Invoice Design. This error will appear when I click on the “Customize & Preview” button.

Please advise.

Best to check the logs in storage/logs/laravel.log

Also, ensure that you have configured a API key using PhantomJS

Thanks for your reply @david

  1. I configured the API key using Phantom.JS as proposed but the same problem still occurs
  2. Below here is the log that appears in laravel.log whenever I click on "Customize & Preview, but I don’t have any clue how to fix it:

It may help to add LOCAL_DOWNLOAD=true to your .env file and then run php artisan optimize

Thanks, @hillel, I really appreciate your feedback. By following your advice, I don’t get the 500 Internal Server Error anymore but now I have different problems. Sometimes the preview will work, and sometimes it doesn’t (Failed to load PDF document).

Tried changing the design option (ie: Modern, Business, Creative) from the drop-down menu and this error will appear randomly. If that happened, I will need to refresh my browser and start all over again.

Any idea? Thanks

Are there any related error in storage/logs?

Nope, no error in the logs. Anyway, I have changed the PDF Generator from “Phantom” to “Snappdf” and it’s working fine now.

PDF_GENERATOR=snappdf
LOCAL_DOWNLOAD=true

Thanks!
