I am trying to understand the mule error object and I am a bit confused with what I see in the debugger.

Say there is a http request call failure in my app and in the debugger I can see the error object with muleMessage property.

And if I right click on error object > copy value then I don’t see muleMessage in there. There it’s called errorMessage. Both holds the same value.

Similarly, for IBM MQ listener. When I look at attributes in the debugger I can see attributes.headers.messageId. Yet, when I capture it in munits using munit recording, the same value is captured in attributes.headers.JMSMessageID in JSON.

Which ones should I be using?
