I'm experiencing problems with native modules dependencies (specifically IBM MQ for js) inside a Google Cloud Function (Node v10) and didn't found anywhere the information I needed, so I've opened this question and answered myself to allow other people to find it in the future.
It worked fine in the Node v8 engine but it is now deprecated. After upgrading the engine to v10 and bumping some packages (following all migration guides regarding my dependencies) the exception is thrown by the ffi-napi package during yarn install, as follows:
ERROR: (gcloud.functions.deploy) OperationError: code=3, message=Build failed: ...s status = napi_get_instance_data(env, &d);

It works fine both locally (OSX Catalina node 10.21) and in Docker (tested in alpine-based node 10 and 12 major tags).
TLDR: It is not supported yet.
I've just found out some needed Native APIs for the IBM MQ package dependencies (ffi-napi specifically) were introduced in Node v10.20 (napi_get_instance_data added in v10.20.0) but Google Cloud Functions is based on Node v10.18.1.
The only work around I found so far is to downgrade the ffi-napi to v2.4.7 using Yarn Resolutions or a custom fork. There is no public information regarding an expected release of the Node v10.20 in the Cloud Functions engine.
