Parity PoA Test chain

Support
#1

I’m experimenting with setting up a test PoA chain using Parity v2.7.3.
After deploying contracts on this network, when I call the methods, I get the below error from RPC.

    {
      "code": -32602,
      "message": "Unknown block number"
    }

Is this related to the params in the chain spec?

    "params":{
            "gasLimitBoundDivisor":"0x400",
            "maximumExtraDataSize":"0x20",
            "minGasLimit":"0x1388",
            "networkID":"0x133c",
            "eip155Transition":0,
            "validateChainIdTransition":0,
            "eip140Transition":0,
            "eip211Transition":0,
            "eip214Transition":0,
            "eip658Transition":0,
            "eip145Transition":0,
            "eip1014Transition":0,
            "eip1052Transition":0,
            "eip1283Transition":0,
            "eip1283DisableTransition":0,
            "eip1283ReenableTransition":0,
            "eip1344Transition":0,
            "eip1706Transition":0,
            "eip1884Transition":0,
            "eip2028Transition":0
        },

Do I have any EIP transition missing which is causing this issue?
