How to fix duplicate key error?

Community Support

Hi all,

in the Rocket.Chat log we find some entries with this error from time to time:

BulkWriteError: E11000 duplicate key error index: rocketchat.rocketchat_message_read_receipt.$roomId_1_userId_1_messageId_1 dup key

Which impacts does this error have? We do not have any negative feedbacks from the user at the moment.

And how can I fix this error? Would it be possible to delete and recreate the index?

Many thanks and best regards
Daniel
