Describe the bug

I request Filecoin.StateReadState and receive an error from Forest, while Lotus (ankr) returns correct results.

To reproduce

Lotus request:

curl -X POST https://rpc.ankr.com/filecoin \
-H "Content-Type: application/json" \
-d '{
  "jsonrpc": "2.0",
  "method": "Filecoin.StateReadState",
  "params": [
    "f01234",
    [
      { "/": "bafy2bzacec2pdpnwwznkbm44dl7ehuyqu5igtupo7r5ejgmvvnrjiywaauhaw" },
      { "/": "bafy2bzaceb6dxlcrvo27q5zycy7tizq7n7nhf3bm7vrijm56lugxj6fpbbfs4" }
    ]
  ],
  "id": 1
}'

Lotus response:

{"id":1,"jsonrpc":"2.0","result":{"Balance":"0","Code":{"/":"bafk2bzacectp5rumce4kekelolp6abrtfbbdjwl3ydjvurmfd6nbk3tott4ks"},"State":{"AllocatedSectors":{"/":"bafy2bzacedgt3fssxtvxnnlrmcwshsf3lyzts52ca744ujq4uwqlzwkst4rcm"},"CurrentDeadline":1,"DeadlineCronActive":false,"Deadlines":{"/":"bafy2bzacedogdgi67tk44dhdetx7mvx65kgb3v4o47gf6xsmejaiwi672n476"},"EarlyTerminations":[0],"FeeDebt":"0","Info":{"/":"bafy2bzacebr6djrnzgpf7fc5pvmke6wwufmfldcosovr6cb5bkmw5nomxorjc"},"InitialPledge":"0","LockedFunds":"0","PreCommitDeposits":"0","PreCommittedSectors":{"/":"bafy2bzaceamp42wmmgr2g2ymg46euououzfyck7szknvfacqscohrvaikwfay"},"PreCommittedSectorsCleanUp":{"/":"bafy2bzaceaa2jny7gkgdwnid4kuldau6bnvgyss5bszo4uy6uikrncvdu5mc2"},"ProvingPeriodStart":3120720,"Sectors":{"/":"bafy2bzaceb47p7svfxpwp7bclt6og7kl73fvrz2fd6owhecugnci55zbcfwd2"},"VestingFunds":null}}}

Forest request:

curl -X POST http://localhost:2345/rpc/v1 \
-H "Content-Type: application/json" \
-d '{
  "jsonrpc": "2.0",
  "method": "Filecoin.StateReadState",
  "params": [
    "f01234",
    [
      { "/": "bafy2bzacec2pdpnwwznkbm44dl7ehuyqu5igtupo7r5ejgmvvnrjiywaauhaw" },
      { "/": "bafy2bzaceb6dxlcrvo27q5zycy7tizq7n7nhf3bm7vrijm56lugxj6fpbbfs4" }
    ]
  ],
  "id": 1
}'

Forest response:

{"jsonrpc":"2.0","id":1,"error":{"code":-32603,"message":"Serialization error for Cbor protocol: TypeMismatch { name: \"CBOR tag\", byte: 0 }"}}

Expected behaviour

Forest returns correct results.

This will be more work to make it the way it works in Lotus. We don't have reflection in Rust. See #5484 for a similar problem.

I might be pushed for time in the coming weeks due to holidays and travelling. @akaladarshi would you like to take it?
