Problem with device tracker tp-link and google maps

Good morning,
I have problems with the platforms for TP-Link device tracker and Google Maps neither of them can start, one from a start-up error and one from a file reading error, does anyone know how to solve?

TP-Link error:

Google Maps error:

    raise InvalidCookies(message)

the configuration of the two components is this:

device_tracker:

  • platform: google_maps
    username: [email protected]
    password: password
  • platform: tplink
    host: 192.168.1.2
    username: “admin”
    password: “password”
    track_new_devices: True
    interval_seconds: 12
    consider_home: 180

Does anyone know how to solve?
