Hi Support,

I'm working on an app service deployed in Azure which uses EO.Pdf to transform html into a PDF. I keep getting the following EO exception when I send a request to the api via postman:

Message": "An error has occurred.",
"ExceptionMessage": "Conversion failed. EvalScript failed because script engine is not ready or is shutdown before the script can finish. Please use QueueScriptCall instead of EvalScript to execute JavaScript code in this case.",

I'm left pretty confused since I don't get any error like this when I test locally (I'm using v20.3.34). Would you possibly have any pointers to resolve this problem? Thanks in advance!

Hi,

Please try to update to the current version and see if that resolves the issue. We have fixed an issue that may cause this problem in build 2021.0.32.0.

Thanks!
