Illegal offset. EE 2.7.2

Message: Illegal string offset 'category_id'

Filename: wb_category_select/ft.wb_category_select.php

Line Number: 298

I'm using multiple categories under one group and one field name in an ece loop generates the above error but still has the correct output. Inside of a tag pair, the error is still there but then nothing is generated.

I dumped the var and the category_id key is missing from the array. I'm not sure if this is a 2.7.2 change in the tables?

I'm seeing the exact same thing in EE 2.7.2. In my case the error is thrown when lopping through a Matrix (v2.5.10) field. The output appears to be coming through just fine.
