Can I adjust how I connect to my RPC?

[phonglnDEV]

Hi everyone, currently, i'm facing issue with block 0: "code":"ERR_ASSERTION","actual":false,"expected":true,"operator":"==","blockHeight":0,"blockHash":"0x....."}} when i using setRpcEndpoint to set connect to my RPC, i tried to search block 0 on my explorer of my chain, it return another error: createType(SignedBlock):: Struct: failed on block: {"header":"Header","extrinsics":"Vec"}:: Struct: failed on extrinsics: Vec:: createType(ExtrinsicV4):: createType(Call):: findMetaCall: Unable to find Call with index [0, 29]/[0,29] . Has anyone faced and resolved this issue? Please help me.
Is it possible to configure the code to connect to the WS of the Subsquid package?
