Reflex 500 Error in One Activator

Hello AkshaykumarK,

welcome to this community forum.

A 500 error probably indicates something went wrong in the backend (server side error).

Then, the issue has a technical source, and is probalby not triggered by yourdata itself. 

Normally, administrators (like those administering the Fabric backend) are notified and will take actions on this level of challenges.

Can you check to see this issue still remains?

if so, provide feedback in the portal itself (via the feedback icon in the right upper corner in the Fabric portal):

And yes, this will be picked up by the product teams.
