M98 of Invalid Macro (axes not homed) does not error (HTTP)

I've got a SBC+MB6HC machine which I'm sending commands to via the POST /machine/code http request. Everything is running 3.5.1 stable.

My config.g has a M564 S1 H1 in it to keep the axes from being moved until homing is complete.
This means that if I send a command like G0 X436.5 Y-105.3 Z5 from the console or an http request, I get the correct error back: Error: G0: insufficient axes homed.
However, when I have a macro /macros/test_limit_macro.g with G0 X436.5 Y-105.3 Z5 as the contents, running M98 P"/macros/test_limit_macro.g" in the console returns the red error line plus a green bar as if the command completed successfully. In addition, running M98 P"/macros/test_limit_macro.g" via http returns an empty string result as if the command completed successfully.

Is this intended? If so it makes it hard to raise a meaningful error in the program that is making the http requests.

If its not a bug, are there any workarounds or alternatives to be able to extract the error output when running a macro via http request?

Cheers,

@tristanryerparke Yes, that is intended. M98 starts the macro successfully but only as soon as the following action fails you get a generic error message. You need to subscribe to the object model to keep track of incoming messages, then you can handle that as well. See here for further API details.
