Did you try to "Clean MQTT" on esphome? I got this error, do you?

Hello,

In esphome dashboard there’s a “clean mqtt” feature that won’t work properly (at least for me).

Anybody found this problem?

Traceback (most recent call last):
  File "/usr/local/bin/esphome", line 33, in <module>
    sys.exit(load_entry_point('esphome', 'console_scripts', 'esphome')())
  File "/opt/esphome/esphome/__main__.py", line 750, in main
    return run_esphome(sys.argv)
  File "/opt/esphome/esphome/__main__.py", line 737, in run_esphome
    rc = POST_CONFIG_ACTIONS[args.command](args, config)

    return clean_mqtt(config, args)

    discovery_prefix = config[CONF_MQTT].get(CONF_DISCOVERY_PREFIX, "homeassistant")
KeyError: 'mqtt'`
