/me results in "you must login first" error

1. define New API Token for the project
2. run export CIRCILECI_TOKEN=<token>
3. run curl -u ${CIRCLECI_TOKEN}: https://circleci.com/api/v2/me

Result:

{
  "message" : "You must log in first."
}

The token needs to be PERSONAL TOKEN, not project API token
