Module did not self-register: drivelist.node

[amaliagruia24]

Hi,

I have an application based on Theia and I am trying to debug the browser and electron applications, both frontend and backend. I am using the debug configurations defined in Theia IDE repo, here . If I try to debug the electron backend & frontend, everything works good. If I try to debug the browser backend using "Launch Browser Backend"/"Launch Browser Backend (eclipse.jdt.ls)", I get this in the debug console:
C:\Users\xxxxx\xxxxx\node_modules\bindings\bindings.js:121
throw e;
^

Error: Module did not self-register: '\?\C:\Users\xxxxxx\xxxx\node_modules\drivelist\build\Release\drivelist.node'.

}

Node.js v18.18.2

If I start the browser application using yarn browser start, it works.
Any suggestions here? The recommended method to try and rebuild electron/browser does not help.

Hey @amaliagruia24,

Sounds like drivelist was compiled for a different version of node. Can you run git clean -xfd and yarn && yarn browser build to rebuild the project? That usually helps.

Specifically, this error (Module did not self-register: '\?\C:\Users\xxxxxx\xxxx\node_modules\drivelist\build\Release\drivelist.node'.) usually occurs when the native modules were not rebuilt. You can manually do so via these scripts.

Note that the launch configuration points to the "unbundled" sources, so you need to rebuild the native modules if you built the Electron variant in between launches. You could try to modify the launch configuration to point to the bundled variant instead, i.e. lib/backend instead of src-gen/backend. Then you don't need the correct native modules at runtime but just at build time. Probably we should adapt this to be the default, as we did in the Theia repo.
