Client.Block() returns nil block ID and invalid block hash

[Denali Marsh]

Updating to tendermint v0.33.3 has impacted the client. Blocks queried with client.Block() always have a nil BlockID and an invalid Block.Hash(). Testnet block 79769927's block hash is 4CD0241B2DFD9A3457EC9B0D66B8F24C4AC1D1AF2FD0C41EFDD5F1172C81A04B.

But client.Block(79769927) returns:

{:0:000000000000 Block{

What's missing

• Block ID is 0:000000000000, should be 4CD0241B2DFD9A3457EC9B0D66B8F24C4AC1D1AF2FD0C41EFDD5F1172C81A04B:1:BE23B3A45B19
• Commit.Height is 0, should be 79769926
• Commit.Signatures is empty
• Block.Hash() is 497ED601A8D9DC5A69039978DEA81BD4230CD5B8B3AE5198BF9C3A78569EA7E4, should be 4CD0241B2DFD9A3457EC9B0D66B8F24C4AC1D1AF2FD0C41EFDD5F1172C81A04B.

@cbarraford I am sorry that #114 have been reverted, because of this issue, binance-chain is based on tendermint v0.32, while v.0.33 have changed a lot about Block structure to save storage.
