Hi there!

This problem is hard to explain with a few words so I'll give you an example directly:

I have two tables: post and user. A post has two relations with the user table: author and moderator. In my app, everyone can see who is the author of a given post but only admins and moderators can see the user who has moderated the post.

So I'm using the authorization middleware to allow access to the moderator column, based on user's role (I do that with authorization.columnHandler).

Then, when I'm trying to list posts with a GET on /records/post?join=user, this error occurs:

{ "code":9999, "message":"Call to a member function getName() on null" }

X-Exception-File	[...]\vendor\mevdschee\php-crud-api\src\Tqdev\PhpCrudApi\Record\RelationJoiner.php:150 X-Exception-Message	Call to a member function getName() on null X-Exception-Name	Error 

I have a simple fix for that, see related PR.

⚠ I really don't know if my fix does not have any side effect.
