IllegalStateException: No executor delegate for eth_getLogs

Tried dshackle for a load balancer in several ETH2.0 clients (Lighthouse, Teku, Nimbus) and got this error: "_IllegalStateException: No executor delegate for eth_getLogs_". The host was Ubuntu 20.04.1. In spite of the error, it seems like working but the long java error message in the log (journalctl) is really annoying. I am attaching the yaml conf file and full log below.

Beside the error, it generates too many _unnecessary_ requests and consumes up the free tier allowance of Infura and Alchemy. It would be great if there was an option for "_minimal requests_". I appreciate this project and it has a very good potential for the load balancer of ETH2.0 clients since this is the only one available at the moment. Thank you.
