Hi Robert,
You mentioned that you were able to successfully generate reports without error earlier in the day, was this on the same record?
If it was not on the same record, can you please try to identify some differences in the reports that were successful and those that were not? i.e. number of pictures, repeats, answered questions for the record. It would be good to know if the report(s) encountering issues have more data in them than those that processed without issue.
Thanks,
Brandon
