#### Receive Large Responses
A GRPC::ResourceExhausted exception is raised when a server response is too large. In particular, this will happen with mainnet DescribeGraph calls. The solution is to raise the default limits by including a channel_args hash when creating our stub.
```ruby
stub = Lnrpc::Lightning::Stub.new(
'localhost:10009',
credentials,
channel_args: {"grpc.max_receive_message_length" => 1024 * 1024 * 50}
)
```
