aws iot MQTT test client not support XML format

Question

I am using the AWS IoT MQTT test client to publish XML data to an MQTT topic,
 but I am encountering an error where the message cannot be displayed in the specified format.

data is 
    26.397156144460933
    55.26943049065625

However, when I check the AWS IoT console, I see the following error:
Message cannot be displayed in specified format.

I suspect the AWS IoT MQTT test client might not support XML format messages. Has anyone else encountered this issue, or does anyone know how to resolve it? Is there a specific configuration or format that needs to be used to display XML messages correctly in the AWS IoT console?

Hi. It doesn't support XML. You'll get the error message, and your payload will be displayed as plain text.

AWS IoT rules engine only parses JSON: https://docs.aws.amazon.com/iot/latest/developerguide/topicdata.html

You can use a free client like mosquitto, or a commercial MQTT test client like MIMIC MQTT Simulator to overcome such limitations.
