N-API callback exception when running above Rosetta

[RichardFoss]

Thanks for your great package!
I am trying to create an app deliverable for an Apple x64 architecture when running on an Apple arm64 architecture. I am using JZZ to send transport command to a DAW, and also to receive MTC messages from the DAW.
I am developing in VSCode, and have ensured that VSCode, its terminal, and node.js are running above the simulated x64 (Rosetta) architecture using arch and node -p "process.arch" commands. I am using JZZ commands to open input and output ports, to send messages, and I have used .connect to ensure the handling of MTC messages.
My app runs, and transport commands I send are successfully received by the DAW. However, the receipt of MTC messages results in a succession of the following message:
(node:41451) [DEP0168] DeprecationWarning: Uncaught N-API callback exception detected, please run node with option --force-node-api-uncaught-exceptions-policy=trueto handle those exceptions properly.
Any idea of how to prevent this callback exception and to pick up the MTC messages?

Hi! Thanks for asking!
Are you writing a VScode extension? In this case, you can try https://github.com/jazz-soft/jazz-midi-vscode
Sorry, I'm not familiar with Rosetta...

[RichardFoss]

Hi, thanks for your response! No, I'm not writing a VSCode extension. I have created an immersive sound client/server program in javascript ( www.immersivedsp.com ). I was hoping to create the Intel Mac updates on my Mac silicon machine, rather than going to a separate Intel Mac. I have got closer to achieving this with JZZ than with other MIDI npm packages, but am just battling with the handling of incoming MTC messages.

I wonder if it helps if you rebuild https://github.com/jazz-soft/jazz-midi (see the node-gyp section) on your system...
I believe the problem must be in that module.

Thanks for following up with further help!

I cloned the jazz-midi folder into a folder in my project, changed to that folder, did an "npm install", and then a "node-gyp rebuild". I got an error indicating no binding file. I saw that there was a binding file in the node-gyp sub-folder, so changed to that and did an "npm install". I got the following error message:

"gyp info spawn args [ 'BUILDTYPE=Release', '-C', 'build' ]
CXX(target) Release/obj.target/jazz/jazz-midi.o
../jazz-midi.cpp:515:9: error: no matching function for call to 'napi_wrap'
XX (napi_wrap(env, self, Plg, destroy, 0, 0));"

I also tried to do a "node-gyp rebuild" here, but again got a similar error message:

gyp info spawn args [ 'BUILDTYPE=Release', '-C', 'build' ]
CXX(target) Release/obj.target/jazz/jazz-midi.o
../jazz-midi.cpp:515:9: error: no matching function for call to 'napi_wrap'
XX (napi_wrap(env, self, Plg, destroy, 0, 0));

There does seem to be a problem with the 'napi_wrap' function? Any ideas about the way forward would be much appreciated!

[jazz-soft]

Ok, this is something... I'll try to track it from there...

[RichardFoss]

Thanks!

[jazz-soft]

Please check out the latest version and see if it compiles...

[RichardFoss]

Thank you very much, it compiles!:

"2 warnings generated.
SOLINK_MODULE(target) Release/jazz.node
gyp info ok "

I tried copying Release/jazz.node into node_modules/jazz-midi/bin/macos64

As before, I could send MIDI transport commands to a DAW, but the returning MTC caused the same error - "-force-node-api-uncaught-exceptions-policy=trueto handle those exceptions properly.
(node:80262) [DEP0168] DeprecationWarning: Uncaught N-API callback exception detected, please run node with option --force-node-api-uncaught-exceptions-policy=trueto handle those exceptions properly."

Is there possibly something else I should be doing with the release build?

[jazz-soft]

should it be called from bin/macos64 or bin/macosa64 ?

[RichardFoss]

Ah, I assumed that it would be bin/macos64. I thought that the 'a' referred to 'arm'. When I place Release/jazz.node into node_modules/jazz-midi/bin/macosa64, the enumeration of MIDI ports doesn't happen, for example this command "midiOutPorts = JZZ().info().outputs;" returns an empty array. So it looks as if jazz.node is indeed called via bin/macosa64, but that my release build doesn't work. It's a bit late where I am now. I will have a further look at this tomorrow. Thanks again for your help.

Could you please give more details about the versions of your OS, node and npm?

[RichardFoss]

macOS is 12.6.3, node is 18.20.3, npm is 10.7.0. I will be updating these all this week, and will have another try. Thanks for your continued support!
