Casting Error in GraphQL C# Library

We are facing a piquant situation using GraphQLClient's SendQueryAsync method to call Monday.com API. The line goes like this

var response = await graphQLClient.SendQueryAsync(request)

If the server returns a proper JSON it is all fine. However if the server returns a message like Complexity budget exhausted, query cost 30001 budget remaining 29984 out of 1000000 reset in 8 seconds, it throws a message like

```
Error converting value Complexity budget exhausted, query cost 30001 budget remaining 29984 out of 1000000 reset in 8 seconds to type GraphQL.GraphQLError. Path errors[0] line 1 position 305
```

How do we configure this graphqlclient to cast the string into GraphQL Error or are we missing something else?
