Cannot read property 'blockUntilReporterExits' of undefined

I receive this error when I follow the mocha example. I have made a PR to solve the problem, but I believe the source of the issue is approvals\lib\Providers\BeforeEachVerifierBase.js It's call to FileApprover.verify(namer, writer, reporterFactory); doesn't pass in any options and GenericDiffReporterBase.report (and other reporters) are written as if it did.

sorry I don't know how to link to a PR. This is my attempt: #123

Thank you for logging this. I am getting this problem too.

I found a workaround for this, which was to revert from 4.0.0-beta.1 to 3.0.5

So using this in package.json:

    "approvals": "^3.0.5",
