Query a collection by an array of document ids with python

Question

I have list of ids I want to query from a collection. If I use:

query = firebase_client.collection('my_collection').where(
    field_path=field_path.FieldPath.document_id(), op_string='in', value=list_of_ids
).stream()

Works, but gives me the warning:

UserWarning: Detected filter using positional arguments. Prefer using the 'filter' keyword argument instead. return query.where(field_path, op_string, value)

I know that if I wanted to query by document field I should use:

query = firebase_client.collection('my_collection').where(
     filter=FieldFilter('field', '==', value)
).stream()

What is the proper way to query a collection by a list of document ids in order to avoid the warning?

When using:

filter=FieldFilter(field_path.FieldPath.document_id(), op_string='in', value=list_of_ids)

The script crashes when trying to read the snapshot in a for loop.

with at the end of the crash message
