Couldn't load options using mocha: child process exited with code 9 and signal null

Trying to add the extension to a project (even an empty project with just one test), and I get the following error:

[Error: Couldn't load options using mocha: child process exited with code 9 and signal null
	at ChildProcess.<anonymous> (/Users/dhowe/.vscode/extensions/hbenl.vscode-mocha-test-adapter-2.14.1/out/optsReader.js:89:32)

I get the same thing. Have have not seen a working sample of this adapter. Mocha runs fine from CLI:
npm test

But when hit the "Refresh Tests" it shows "Test discovery failed" and opens this:
`
The worker process finished with code 1 and signal null
