Document Generation error : It seems there was an error on the server.

Thanks Raymond, I am facing the same problem, using Office 365.  I also tried https://documentservices.adobe.com/dc-docgen-playground/index.html#/ Ibut same error message.  "it seems there was an error on the server".

My JSON file is quite simple.   Here's the output from NOTEPAD.

It only works if I have one "record"  e.g.

{"No.":28,"Name in Chinese":"符露","Name in English":"Fu Lu","Date":"3rd March 2024","Event":"Marine Tour at Hoi Ha Wan"}

Any insights, or how to format the JSON correctly for the Document Generator API to work. ?

Thanks

Um, no. I work for Adobe, on this team, and can you tell this is the right forum for that question. Now to be clear, this is *not* the same as paid technical support, but this is the right forum.
