Meetup will be deprecating the REST API and replacing it with GraphQL. The REST API will be deprecated at the end of 2021, and the GraphQL API is already active. Therefore, for this package to remain usable, we have to replace the guts. The ghql package could be useful.

Here’s the info on migrating from REST to GraphQL: https://www.meetup.com/api/migrating
