Checklist - Configurable forms throwing error for some employees

Content

Hi Team,

As part of checklist task of type 'Onboarding" - we have configured the "Configurable forms" to get the data from the employee. Most of the employees are able to access the task and complete it but around 2-3% employees are getting error - "An error occurred. Contact your help desk"

Every one has same role but not sure why only few of them are getting this error.

Also if we delete these tasks and reassign them from library (exact same task) - it works fine.

If anyone faced similar issue and have any thoughts to resolve it please let me know.
