Graph-node : WARN Trying again after eth_getBlockByNumber(0, false) RPC call failed (attempt #10) with result Err(Decoder error: Error("invalid length 1, expected a 0x-prefixed hex string with length of 16", line: 0, column: 0))

Summary of Bug

1. Describe

I try to deploy a graph-node and when start it fails.
The error message is :WARN Trying again after eth_getBlockByNumber(0, false) RPC call failed (attempt #10) with result Err(Decoder error: Error("invalid length 1, expected a 0x-prefixed hex string with length of 16", line: 0, column: 0)), provider: mainnet-rpc-0
I try to use the curl command: curl https://exchaintest.okexcn.com -X POST -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","method":"eth_getBlockByNumber","params":["0", false],"id":1}'
and it returns the error:{"jsonrpc":"2.0","id":1,"error":{"code":-32602,"message":"invalid argument 0: hex string without 0x prefix"}}
if I change the params "0" to "0x0" will be OK. But I can't change the graph-node's code.So the error messages caused the
graph-node fail.
