1. Logon to Onboarding
2. Complete the process 
3. Click next on a panel or submit the process
4. error displays

There are numerous causes for this issue, for this particular case it is that the Max Length of the text field is set to 1000 and the key is used as an Index field in Super Admin

1. The Max Length of an Index Field is 300
2. By using the Key as an Index field in Super Admin > Processes > Click on Index Fields beside Process
3. You're Contradicting what you want on the panel to the Index Fields logic 
4. I suggest either using a key that is not an Index Field on the panel or Deleting the current key as Index Field
