GraphQL.Client not returning results, but server completes the request

I am unable to retrieve the results of the GraphQL query response returned. The server logs that the request was finished with no error. But the program continues to wait for a response. In the code provided, the Debug.Print statement following the await graphQLHttpClient.SendQueryAsync is never reached. It just indefinitely hangs at this statement and there is not timeout or error.

This code is executed in the ViewModel initializer.
