Just as the title suggests, we need more descriptive errors. My implementation has had a sudden error thrown, but there were no changes prior to the error. Instead, DocGen gives me a very general error, "A report has missing or invalid data".
This error doesn't help me, and even Nintex's support can't help. We have 11 reports associated with this DDP and there's no way of knowing which report is causing the error. It could at least specify the record ID of the report causing the error.
