ContentOperationNotPermittedError

[barry1955]

We have been using the mvlabs snappy for a few years now.
Recently we were testing a new release and we ran into an issue whereby the mvlabs pdf service is not working as before.

I get this above error now but as far as the team is aware we have made no changes to any code that touches the module.

See error listing below

I note that is is including file from c:\windows\temp - which is outside the document root. would this cause the issue on an SSL site?

Hi @barry1955, I think that could be a problem related to one asset in the html (css, js, images). Below you'll find the final command using wkhtmltopdf executed from Snappy, in way to test it from command line:

/usr/local/bin/wkhtmltopdf.exe --lowquality --margin-bottom "0" --margin-left "6" --margin-right "0" --margin-top "4" --orientation "Landscape" --page-size "A4" --javascript-delay "6000" --zoom "1.2" "C:\WINDOWS\TEMP\knp_snappy5b7b5844bbdec8.14741832.html

Thank you very much for the feedback, I've been on the road for 2 weeks, hopefully I'll get this resolved soon.

We use the htmltoPdf tool to allow printing out of maps, and the existing code has been working in-situ for a while now, the main difference has been the inclusion of SSL.

Again, thank you for the response, I'll be looking into this today.
