Looks like https://github.com/dnadesign/silverstripe-elemental/blob/4.0/src/GraphQL/ReadOneAreaResolver.php#L15 is being passed an invalid ID.

In the first instance it could throw an error along the lines of "Can't find ElementArea {$args['ID']}". That might shed some light on why this was triggered.

[ScopeyNZ]

Yeah we'll be happy to accept a patch that at least asserts the area exists before checking permission.

Nevermind I just did it: #623

With this patch it'll throw a different error. You probably want there to be no error but without additional detail there's no way I know to know what's going on 😅 .

[robbieaverill]

Fixed by #623?

[robbieaverill]

The fix is what I would've expected to do to fix this error, so closing as "fixed"
