We receive an error while uploading a form to aggregate. It says HTTP Status 400 - Bad Request.

A little more information.
We added the column "bind::odk:length" to these form and set text responses to "99999" to allow the text field to accept 99999 characters since ODK sets text fields to a total of 250 characters for text responses, which was causing problems if responses require longer entries, then they were cut off. Is there another way to increase the limit without using the bind column?
