I try to run the functions emulator with firebase emulators:start and get an error:

Answer 1

Sorry for this everyone, it was my fault. In version 3.15.0 and 3.15.1 of the firebase-functions SDK we refactored some of our file hierarchy without realizing that the emulator team monkey-patched an undocumented file/function.

The upcoming version 3.15.2 of firebase-tools handles both the old and new path. You can fix the error with:

npm install -g firebase-tools
