TypeError when editing any element

I don't think this is happening to the rest of us so the steps to reproduce need refinement.

What kind of information do you need @jrockowitz?

New info, this happens when a use has the roles "Site Owner, User Manager, Content Publisher".

Can you reproduce this on a freshly-installed site? If not then we need more information.

Sadly, I wasn't able to reproduce the issue on a freshly installed site. What more information do you need?

We shall have to understand what differs between the site in question and a freshly-installed site. The current steps to reproduce in the issue summary are irreproducible by you. As a start it may be interesting to know the string value of $form_state->getValue($element['#parents'] to begin inferring why it is a string.

Hmm... Not sure if this should be reopened or not.

I'm experiencing this exact issue, down to the line number.

My state of play:
PHP 8.2.11
I'm upgrading an existing site to Drupal 10.0.15 (for reasons) from Drupal 9.5.10.
I'm going from Webform 6.2.0-beta6 to Webform 6.2.0-rc2
I have the following additional webform modules installed:
* Webform Image Select
* Webform UI

I've seen similar errors in my searching on this too. I'm at the end of my day. I'll try and prep a patch for this tomorrow though. If it is a low impact thing hopefully it will be considered.

Please see #9 as more information is needed.

I have updated for this issue in attached patch

@Mohd Sahzad, you're a rockstar.

it was a nice surprise to start work this morning and find this here. Cheers for that. :)

This did the trick for me and gets my RTBC+1.

I've deployed this to a test environment that the client has access to and it's working well there as well.

The patch in #14 adds two lines of extra whitespace.

It should only call ::getValue() once. Store the return value in a variable and check that for being an array.

I have update the patch for #14 & generated MR as well, please review.
