this is a custom transformer https://hub.safe.com/publishers/safe-lab/transformers/html2pdfconvertor and reading over the usage and Output Ports section, you’ll find:

• Page size, which either can be chosen from the standard list (Letter, Legal, A4 etc) or specified in points as two space-separated integer numbers (width and height);

The rejection code or message should give you the hint on where the issue is?

I can also see you have a ‘list’ as the PDF output name. You might need a ListExploder prior to this HTML2PDFConvertor 

​@j.botterill and ​@raghavendrans - Thank you for your respond. We solved the problem and it is now running again. the problem was the connection to the .exe-file using FME flow.
