Could this be closed? #422?

My pr is only for the module. Looks like #422 is also talking about the component. Therefore: I don't know.

Hi, I installed com_weblinks 4.0.0-dev in Joomla version, ‎4.0.0-beta8-dev.

I receive an error at administrator/index.php?option=com_categories&extension=com_weblinks

1054 Unknown column 'c.published' in 'field list'

Which com_weblinks should I have installed?

@ReLater If you look at the model class, it could return false https://github.com/joomla-extensions/weblinks/blob/master/src/components/com_weblinks/models/category.php#L76 (in case database failure) and for that case, the error still happens.

I updated your PR abit to return empty array for that case. Hope that is OK for you.

Before patch, there is an error

After patch, the error is gone.

So I will merge this PR and we can continue working on other issues. Thanks !
