Hello @tarafield2015,
Thanks for the details. 
There is currently an issue from our side with the new action and the conversion is failing for some reason. Our developer team has already been notified, we will fix this issue as soon as possible and get back to you.
In the meantime, please remove “Generate pdf from HTML server-side ConvertortoPDFv2.0 A” and use only the Convert PDF converter action. Screenshot by Lightshot
In case the issue still persists, would it be convenient for you to share access to your app? This will allow us to identify any possible cause much faster.
For this please add our [email protected] email as a collaborator of your app (disregard the warning, our email can be added to the collaborator list even if your app is on the Free plan).
Looking forward to your reply.
Best regards,
Zeroqode Support Team
