Bunch of missing schema errors when adding ECA bulk operations

Thanks for the bug report. I've pushed a possible fix into the development state of 1.0.x, let me know if that works for you.

There may still errors be reported like these ones:

variable type is integer but applied schema class is Drupal\Core\TypedData\Plugin\DataType\BooleanData
variable type is string but applied schema class is Drupal\Core\TypedData\Plugin\DataType\IntegerData

In such a case, you'd need to go into the according View configuration (via UI) and just click on save without changing anything. Then the errors are supposed to go away. Export your configuration to apply those changes so that they'll match up with the properly defined schema.

Assuming to be fixed. Feel free to re-open if the problem persists.
