I’ve searched and searched and couldn’t find similar issues. Here is my current situation:
Self Hosted v5.5.20
Ubuntu 18.04 VPS on Digital Ocean
I have been using the hostedpdf for some time but decided to revisit getting snappdf to work today. Enabled debugging and the endpoint /api/v1/live_preview?entity=invoice returns the output below.
I discovered snappdf was not working from the CLI when trying vendor/bin/snappdf convert --html "<h1>Hello world</h1>" test.pdf from root of invoiceninja5
Installed additional dependencies and “snappdf convert” is now working and generating PDF as expected however the live_preview endpoint is still returning the response below.
Any suggestions would be greatly appreciated.
