System Error when adding a document channel in Intelligent Document Processing

Certified Associate Developer

Hi Team,

In my Appian community edition (ACE) environment, I am facing issue while adding a document channel in Intelligent Document Processing site under configure.

It adds the document channel and update the cloud database dudocchannel table but error occurred while creating the supporting groups. After looking at Process Model, I found below error. Due to which none of the group is getting created and I am unable to add those group to IDP project to use further.

Please suggest if any solutions to it.
