Description

• generate a typescript angular package with configured bearer auth like

  securitySchemes:
    bearerAuth:
      type: http
      scheme: bearer
      bearerFormat: JWT

• and the result in the generated package is that it trys to use basic authentication with username and password
• the expected behaviour is too send the bearer token in the header of the api request
