Error and need everyone's help!

Can anyone help me explain this error and how to fix it? I’m working on a bookstore site project but I’m having a hard time figuring out how to create the interface!

Hey @Hung_Viet, a quick search of these forums for the error you listed would surface an answer to your question.

See Option usecreateindex is not supported - #4 by Stennie_X for further details.

To fix the error, please comment out line numbers 41 and 42.

This error occurred because useCreateIndex and useFindAndModify are no longer supported.
