I can confirm that the above code returns $values as either a string or an array. We are overriding the template in our theme to access {{ locality.code }} which breaks when $values is a string. Attached is the patch removing the code.

https://git.drupalcode.org/project/address/-/merge_requests/65 does the same as the attached patch, and adds test data.

Thank you, @oheller!
The patch from #7 🐛 Plain Text Formatter does not set Locality properly Active to remove the hasChildren() check in the AddressPlainFormatter resolves the issue.
I encountered this exact problem where address plain templates using {{ locality.code }} would break with the InvalidArgumentException. The fix ensures that locality data is consistently structured as an array with code/name keys.
I tested it with US addresses.

It looks good to me, but someone else should test and validate the change.

Confirmed the fix works.
