Pagination issue with airtable api

[andyshinn]

I am trying to query the Airtable List Records API using pagination offset (which appears to be how they paginate). But it fails with the error:

error while performing the infinity query. unsuccessful HTTP response. 422 Unprocessable Entity unsuccessful HTTP response. 422 Unprocessable Entity unsuccessful HTTP response. 422 Unprocessable Entity

If I don't set offset for the pagination field then it works but only returns 100 records (and I have about 500). I also can't see the query it is making so not sure if maybe it is submitting an empty offset with the first request and maybe that is why it fails?
