Data Lake Collection Import Authentication Failed in Realm Function

While I was inquiring about the document in the data lake collection in Realm Function, the following authentication failure error occurred

“uncaught promise rejection: error connecting to MongoDB service cluster: failed to ping: connection() error occured during connection handshake: auth error: sasl conversation error: unable to authenticate using mechanism “SCRAM-SHA-1”: (AuthenticationFailed) authentication failed, correlationID = 16c6f0d3ebf9520e6397ad2e”

The function script is as follows.

exports = async function(changeEvent) {
  const user =
  let result = user.findOne({});

Can you tell me what I should do to solve this error?
