For some reason in our state environment I am getting the following exception from the default form submit controller. It doesn't appear to happen locally or in production but I have noticed this error and I'm wondering if this is a database issue. I can create a basic form with 2 fields and the form submits fine. If I go back to add another field, copy the form, or do anything the form breaks.
I was once using custom form container block but we have since switched off of it due to an error (currently open thread related to that).

Anyone have any idea wha'ts going on here?
EDIT:
This appears to only occur on 2nd submission and beyond. Does not occur on the first submission of a form
EDIT Again:
For some reason it behaves perfectly in my local environment. It only breaks when hosted in IIS (and multiple sites are having the issue). I reverted my form customizations, ran the remote DB that IIS is running from locally and do not have any issues. It's only when running in IIS for some reason.
Because it only happens on your specific setup (I guess), could you please open a SupportCase and provide us your database and IIS site. We are happy to help. Thank you.
