"failed to load state tree" and "failed to load hamt node" error when get message

When I call Filecoin.ChainGetBlockMessages like this:
curl -X POST ‘https://filecoin.infura.io’ --data ‘{“id”:0,“jsonrpc”:“2.0”,“method”:“Filecoin.ChainGetBlockMessages”,“params”:[{"/":“bafy2bzaceazp6xtozvl4my256x6dnzf2xzj3h6kpssrn4mc47janrdleldpks”}]}’

I got “blockstore: block not found” error.
{“jsonrpc”:“2.0”,“id”:0,“error”:{“code”:1,“message”:“failed to load msgmeta (bafy2bzaceasyv65rehueiavr2acqvowbzrilg7aatcwj2jck5zvgutaslbhgw): blockstore: block not found”}}

When I call Filecoin.ChainGetParentMessages like this:
curl -X POST ‘https://filecoin.infura.io’ --data ‘{“id”:0,“jsonrpc”:“2.0”,“method”:“Filecoin.ChainGetParentMessages”,“params”:[{"/":“bafy2bzaceazp6xtozvl4my256x6dnzf2xzj3h6kpssrn4mc47janrdleldpks”}]}’

I got “failed to load state tree” error and “failed to load hamt node: blockstore: block not found” error
