Steps to replicate the issue (include links if applicable):

• Access MPIC either on staging or production.
• Open the form for creating a new data collection artifact
• Provide all the necessary details but leave the "Description" field empty (note that it is labeled as optional)
• Attempt to submit the form

What happens?:

A validation error is thrown, stating that the "Description" field has an invalid value, even though the field is marked as optional. The error message displayed is:

"There are some errors while validating the form description: Invalid value"

(See attached screenshot)

What should have happened instead?:

Since the "Description" field is optional, the form should submit successfully without requiring a value for this field. No validation error should be triggered if the field is left empty.
