Jira error should be readable and understandable.

Issue Summary

Jira error should be readable and understandable.

Steps to Reproduce

1. Create a custom field Component.
2. On the create transition, add a post function so that the value of field components will be cleared.
   On the next transition, add a validator so that the field Components should be modified during the transition.
   The component field should also be a mandatory field during the create screen.

Expected Results

During the seconds transition, the system should throw custom error since the component field should be modified and was cleared in the create transition.

Actual Results

Unreadable error message

Workaround

Deleting the post function “The value of field Components” under create transition resolves the issue.
