Ticket: update Comment

I have pass all the tests in Create/Update Comments. But the only test fails is for testUserFailsUpdateOthersComments(). I have the following error log:
"com.mongodb.MongoWriteException: E11000 duplicate key error collection: 5c63e39e014b76270bf72a53_mflix.comments index: id dup key: { : ObjectId(‘5c755f17ecb8973070513d4a’) "

Any help?

print in terminal: mongo “mongodb+srv://XXX/mflix” --username m220student --password m220password --eval ‘db.comments.drop()’

where xxx is you atlas url

I have tried but the issue is still there?
