Error with date fields about weewx-mqttsubscribe

Forgot to say: using version 2.1.0

Your json payload is

{
  "battery":71,
  "humidity":43.77,
  "last_seen":"2022-05-18T14:25:08-03:00",
  "linkquality":98,
  "temperature":21.13,
  "voltage":2900
}

MQTTSubscribe attempts to convert all incoming data to float. The easisest, if you don't care about last_seen is to ignore it.

        [[[zigbee2mqtt/Escritorio_-_Temperatura]]]
            [[[[message]]]]
                type = json
            [[[[temperature]]]]
                name = inTemp
            [[[[last_seen]]]]
                ignore = true

Alternately you could keep it as a string

        [[[zigbee2mqtt/Escritorio_-_Temperatura]]]
            [[[[message]]]]
                type = json
            [[[[temperature]]]]
                name = inTemp
            [[[[last_seen]]]]
                conversion_type = none

Tks! I will try this tonorrow.

One sugestion is to parse only specified fields from condifuration. I mean, default state would be ignore and just include fields from condiguration.

Agree that if I was starting from scratch, 'opt in' woukd make sense. When I started I wanted everyting in the json and now with MQTTSubscribe 3 years old, I am hesitate to make that kind of breaking change.
If one wants to 'opt in', you could do something like this.

        [[[zigbee2mqtt/Escritorio_-_Temperatura]]]
            ignore = true
            [[[[message]]]]
                type = json
            [[[[temperature]]]]
                name = inTemp
                ignore = false
