I am having a problem using jest to write unit tests for a dynamic resource. when testing the outputs, e.g.:

describe("my custom resource", () => {
    it("has outputs", function(done) {
        pulumi
            .all([myCustomResource.someOutput])
            .apply(([someOutput]) => {
                try {
                    assert.equal(someOutput, "foobar");
                    done();
                } catch (e) {
                    done(e);
                }
            });
    });
});

I am seeing these errors:
