Error channel reports `'NoneType' object has no attribute 'endswith'`

[amotl]

Hi there,

lovely users of Kotori just reported this message observed on the MQTT error topic error.json. The error message could be improved, to let users diagnose the problem better.

basic/foo/test/EnvR//error.json {
    "type": "<class 'AttributeError'>",
    "message": "'NoneType' object has no attribute 'endswith'",
    "description": "Error processing MQTT message \"b'{\"time\" : \"2023-03-03 23:39:30\", \"model\" : \"ACME Foo\", \"dev_id\" : 77, \"power0\" : 125, \"power1\" : 5109, \"power2\" : 4992}'\" from topic \"basic/foo/test/EnvR/\".",
    "timestamp": "2023-03-03T22:39:30+00:00"
}

With kind regards, Andreas.
