Can't help exactly here, but which Report is the ID 614893e27d813993b

Then you need to remove a couple of field and see if it work, sound like one of the field need to be "Countable", e.g. it can't be a single field type such as "Name, Date of Birth", which is usually a Varchar field or a Date/Numbers field. It need to be an "array" fieldtype. Where you can input multiple value or date, for example tag, keywords or categories are usually what I use for array field.

This would be my guess from the log. But digging through your report and see which field is cause this error would help you find out why it is not working.
