ContainsFilter is raising an exception

[mikeengland]

The ContainsFilter is raising an exception when it is used.

Example call:
res = searchads_slicer.highcharts.line_chart(
metrics=['clicks'],
dimensions=['date'],
dimension_filters=[RangeFilter('date', date.today() - timedelta(days=14), date.today()),
ContainsFilter('device_type', ['c'])],
)

print(res)

print(json.dumps(res))```

Error:

Traceback (most recent call last): File "", line 205, in <module> ContainsFilter('device_type', ['c', 't'])], File "/site-packages/fireant/slicer/managers.py", line 280, in _get_and_transform_data references=references, operations=operations) File "/site-packages/fireant/slicer/managers.py", line 69, in data references=references, operations=operations) File "site-packages/fireant/slicer/managers.py", line 103, in query_schema self._default_dimension_definition), File "site-packages/fireant/slicer/managers.py", line 205, in _filters_schema filters_schema.append(f.schemas(definition)) File "site-packages/fireant/slicer/filters.py", line 58, in schemas return element.isin(self.values) AttributeError: 'Coalesce' object has no attribute 'isin'
