Indexing of XinFin network which is fork of ethereum using TheGraph

I am trying to connect XinFIn testnet with graph-node
Following these steps graph-node/docker at master · graphprotocol/graph-node · GitHub for graph-node configuration

Having this error in logs

RPC call failed (attempt #10) with result Err(Decoder error: Error("0x prefix is missing"
Is there any option in graph-node to make this prefix configurable? so that we can use xdc prefix rather than 0x?
