Device simulator phone app message crash

I'm trying to use Communications.PhoneAppMessage and I'm following the example given in the Toybox API documentation as:

using Communications;
// set up somewhere to store the message
var message = new Communications.PhoneAppMessage;
// set up phoneMessageCallback
function phoneMessageCallback(msg) {
message = msg.data;
}
// register the messages from the callback to capture the results
Communications.registerForPhoneAppMessages(method(:phoneMessageCallback));

In the Connect IQ Device simulator, I use the menu entry: Simulation/Phone App Message and I enter {"my message"}. The simulator crash with:
Error: JSON Error
Stack:

Encountered app crash.

On macOs 12.2.1 with connectiq-sdk-mac-4.0.9-2022-01-24-2154651d3

    While trying different things, I realize that if I send the following message the app don't crash:
    {
    "data":"My message"
    }

    Then, msg.data.toString() = "{data=>My message}"

    Is there some special requirement on the structure of the message? If so, it would be nice to clarify in the documentation since it is not clear from the Toybox.Communications.PhoneAppMessage description.
