Feedback on Sub-Document Operations | Couchbase Docs

Replace is not working in sub-document operations:

Code:
import couchbase.subdocument as SD
db._adapter.collection.mutate_in('airline1', (SD.replace('name', 'Arslan Airways')))
print(db._adapter.getDocument(docids =['airline1']))

error: Traceback (most recent call last):
File "/Users/user/Documents/pydal/test.py", line 90, in <module>
