[Node] MongoError: E11000 duplicate key error collection

[Marcio dos Santos Amorim]

Good morning my friends

I would like to share that I tried to log in and this error came up.

Which returns the error "[Node] MongoError: E11000 duplicate key error collection: microsoft_typescript_node.users index: email_1 dup key: { email: "[e-mail]" }"

Then when accessing it worked again

I've done some simulations to create an account again but I couldn't get this error

I appreciate if you can help me

Looks like race condition from two instances of the application (say, we resubmiting login creation form twice)
