HR Specialists receive error when creating a job requisition: There are too many characters

Summary:

We had made the posting description section read-only for HR Specialists through HCM Design studio by making Enter Custom External Posting Description and Enter Custom Internal Posting Description as Not Visible to HR Specialists

However, now, when requisitions are created, they get an error when trying to submit or save and close on the create job requisition page.

This is probably referring to the posting short description which should auto-populate from the respective job profile. However the short description on the profile is 750 characters. Additionally, this error message does not show when the posting description fields are made editable
