Hi there! I have a question about a weird behaviour I'm experiencing in the Desk tool.
Description: the Desk tool crashes when I empty the array-type field by deleting the
existing document.

              name: 'domain',
              type: 'array',
              title: 'Domain',
              of: [{ type: 'restricted_domain' }],
              hidden: .....,
              validation: (Rule) =>
Basically when I delete the last
Desk tool crashes with the error
TypeError: Cannot read properties of undefined (reading 'length')
I think that something similar was raised 
here . Any idea how I can stop that behaviour?

Hi Debora. Thank your for reporting, and sorry you've ran into this! Please can you let me know which version of Sanity Studio you're using? If you could paste the output of the
sanity versions
command, that would be perfect.

(it also fails without the custom validation Rule I created and the hidden property)

Would it be possible for you to update to the latest version (by running
sanity upgrade
), just to eliminate that as a potential issue?
