Views FieldBase.php TypeError: Unsupported operand types: array + null

@Nickstedt , I have fixed the issue . please kindly review the patch file

The patch does not add the data in both cases.
i used the following construct:

  $field_data['field'] ??= [];
  $field_data['field'] += $data[$table_name]['delta']['field'];

Since it breaks you system, i will release now.

I just updated to 1.15 and it seems to be broken

TypeError: Unsupported operand types: array + null in Drupal\office_hours\Plugin\views\field\FieldBase::viewsFieldData() (line 81 of modules/contrib/office_hours/src/Plugin/views/field/FieldBase.php).

Ditto: we just updated to 1.15 and it seems to be broken for us as well. I don't see that the patch, or the "construct," are in the new code.

Please make sure that you truly have 1.15. It was released shortly after 1.14, which does not have the patch.
Also make sure that all caches are refreshed.
Please report back. I will check again.

Sure. I just ran composer update and it had nothing new.

Please test new dev version.

The patch removes the error message, but does not resolve the root cause.
I do not understand this this can happen.
You may have problems using the new 'season' and 'timeslot' fields in Views (to be used as columns in a view).

The dev version works for me. The site I'm testing with loads now, without errors. It was not using new "season" fields.

I can see the new code from the patch in this version of FieldBase.php, and I couldn't in 1.15, so that looks better.

I am concerned about "does not resolve the root cause."

Thanks for your work on this!

Thanks for your help.
