Print Designer – Print Preview Not Showing (v15)

I’m currently facing an issue with the Frappe Print Designer where the Print Preview does not load or show anything .

What I’ve Tried:

  • bench update
  • bench build
  • bench clear-cache
  • Restarted bench and browser

Despite these steps, the issue persists. There are no visible errors in the UI

Environment Details:

  • ERPNext: v15.63.0 (version-15)
  • Frappe Framework: v15.69.2 (version-15)
  • Print Designer: v1.x.x-develop (develop branch)
  • Payments: v0.0.1 (develop)
  • wkhtmltopdf: 0.12.6 (with patched Qt)

Has anyone else experienced this issue with the Print Designer? Any guidance or fixes would be greatly appreciated!

Thanks in advance.
