Any suggestions? I’m suddenly getting this perplexing message on a test — this is a new project but this test (and the whole repo in fact) are based on our template project, where I don’t get this error. I really can’t find any information about this.

FAIL  src/__tests__/pact/consumer.pact.ts
  ● Test suite failed to run

    The v4 package is currently in beta and requires the 'ENABLE_FEATURE_V4' environment variable to be set

        | ^
      2 | import path from 'path';

version in

package.json

(same as in the other project where it works):

"@pact-foundation/pact": "^10.1.4",

Well, did you set the env var? :) https://github.com/pact-foundation/pact-js/commit/8897da76bdf145f0d3ffb53f7fca14cde2f659a9

Yes, apologies. The feature toggle was at the top of the module which was being exported to the top level index. It should only have existed in one version.

"@pact-foundation/pact": "^10.1.4",

I don’t think the V4 interface was in that package, so my guess is that you actually have a later version installed (

^

allows minor versions to be installed)

So just doing an

npm i

should fix it.

I think so

Aha — thanks all. I will check this in the morning.

All sorted?
