Open a case with state open
Click Close Case button without filling resolution details mandatory fields.
Two error messages are shown
One says :The following mandatory fields are not filled in:

Other says : The following fields contain errors: Resolution code Resolution notes

It happens when close case is clicked for the first time.

The issue can be resolved by modifying the existing client script 'Validate Resolution Information (Case)'.
The workaround script has been added to the attached client script. Importing the attached Client script resolves the issue.
