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:

"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!
