Adobe Document generation api 500 internal service error on bigger files

Facing an issue related to docuemtn genration size.  When I try adding too many images or images that are too large to the word template, the API fails, but if I scale back the number of images or crop some of the larger photos down, it will successfully generate the document.

Is the adobe API failing? surely it needs to handle bigger docuements.  Is there a tech support line?
