Endpoint fails when re-updating a form with a readOnly property without refreshing the page

[hlayisanimazuze]

If a details view is updated and saved successfully, attempting to update the values again without refreshing the form causes the endpoint to throw an error, indicating that the readOnly property cannot be updated. This can be from additional fields to fetch or a readOnly field being added to the form.

Steps to reproduce the behavior:

1. Go to 'https://functional-adminportal-test.azurewebsites.net/dynamic/TestModule/components-details?id=a863d661-e36d-40ae-8e38-23fcbb0467c8'
2. Open developer console
3. Click on 'edit' pencil
4. Update the value
5. Save the changes
6. Click edit again
7. Update the values
8. Save the changes
9. Actual Results: The endpoint displays 400 error status(your request is not valid, property fullName is readOnly). See attached video: https://jam.dev/c/4810d36e-5c91-4282-99fd-b1fcb8ee7fec

Expected behavior
Upon re-updating without refreshing, the endpoint should pass successfully without failing, just how it behaves the first time updating
