## Description
When we enable rosetta from the chain with non-zero initial height & huge genesis, it always return
```
Error: rosetta: (502) bad gateway
```
This is due to huge genesis load rejection from Tendermint.
In current implementation, rosetta server requests genesis to get initial height
```
c.tmRPC.Genesis(ctx)
```
but, this will be failed with below message when the genesis is huge
```
{
"jsonrpc": "2.0",
"id": -1,
"error": {
"code": -32603,
"message": "Internal error",
"data": "genesis response is large, please use the genesis_chunked API instead"
}
}
```
To fix this, we can use following lines
```
status, err := c.tmRPC. GenesisChunked(ctx)
```
