Unable to Generate or Preview Invoices - Page Stuck in Loading Stat

[Venkateshvenki404224]

I am facing an issue while generating and previewing invoices in Frappe. Whenever I try to generate an invoice that is designed using print designer or access the preview, the page enters a loading state and eventually shows an error. However, the error logs do not display any related information, making it difficult to debug the issue.

I am using Print Designer Version:

print_designer 1.2.0

The api request for generating the pdf is getting failed :

I would appreciate any guidance on how to troubleshoot or resolve this issue. Is there a way to enable more detailed logging to capture what’s going wrong? Or are there known issues or fixes for this behavior in the current version?

Thank you for your support!

I get the same error message. The LOG says that I cannot access the .jpg because it does not exist. but that is not true. the file exists, the user and access rights are also correct.
