Question About Document Parser Job Failing

Greetings,

I was testing out the new Document Parser. Sometimes I would have a response saying the following:
 

We had trouble parsing your document

Our team has been notified and will look into the issue. If you get stuck, contact support for help.

Occasionally, I would get a successful parse, but I also get these failed parse jobs. I am unsure of the cause of the failure or whether the failure is preventable on the client side. I was wondering if someone could provide insight as to why the failure might be occurring.

Thanks,

Gabriel
