Using query.next() with no parameters does not work as specified

Description of the issue

I'm implementing an HTTP triggered Azure function to query my DPS for the list of enrolment group registration states using the azure-iot-provisioning-server module. I create the client, construct the query spec and when I trigger the query using query.next() the function throws and error.

When I modify the execution of the query, to use the query callback and wrap that in a promise, I can work around this issue. But the API does not seem to work as written.

Code sample exhibiting the issue

    // Inside and `async` function
    const dpsClient = ProvisioningServiceClient.fromConnectionString(dpsConnStr)
    const query = dpsClient.createEnrollmentGroupDeviceRegistrationStateQuery({
        query: '*'
    }, enrollmentGroupId, 500)
    const { responseBody } = await query.next()
    // BOOM!

@khendry - I got a fix for this committed to master, but I just missed the 11/2 release (1.8.7 I think).

[erikerikson]

The associated fix is neither in the official version or @latest. Is there a release timeline?

[BertKleewein]

@erikerikson - I am checking with the release team

[anthonyvercolano]

This will be in the next release. I am hoping within the next 10 days.
