firebase-tools: firebase serve fails: Failed to emulate

Version info

3.18.4

Platform Information

OS X

Steps to reproduce

firebase serve

This appears to be a project-specific error. It fails for this particular project, but works for another Firebase functions emulation on the same machine.

firebase functions:shell

This fails with the exact same error.

Expected behavior

I expect it to launch the local functions server without erroring.

Actual behavior

=== Serving from '/Users/govinda/Sites/projects/myproject/api'...

⚠  functions: Failed to emulate api

What do value and range represent? Apparently I’m out of it.
