Exported genesis can't be validated using gaiad validate-genesis

[uditvira]

Summary of Bug

If you use gaiad validate-genesis to validate an exported genesis from the Cosmos Hub mainnet, you get the following error:

Error: error validating genesis file mainnet-genesis.json: name field cannot be blank

This was reproduced by @ASoTNetworks

Version

I've reproduced this with gaiad 6.00 and 6.0.4

Steps to Reproduce

1. Stop a synced node
2. Export a genesis file gaiad --for-zero-height --height=9961097 &> mainnet-genesis.json (Notice I need to use &> and not > to dump contents into a file, because gaiad is writing output to stderr and not stdout. This is an unrelated issue)
3. gaiad validate-genesis mainnet-genesis.json

@alexanderbez you helped confirm this issue, is there a summary of what needs to be fixed in a future release to address the issue?

[glnro]

Yeah just to confirm this would be in Rho...we'd need to add two lines I think in SetUpgradeHandler

banktypes.DefaultGenesisState().DenomMetadata[0].Name = "Cosmos Hub Atom"
banktypes.DefaultGenesisState().DenomMetadata[0].Symbol = "ATOM"

hi, here is the fix for export to stdout, not stderr.
cosmos/cosmos-sdk#11844

@uditvira, can you please check the beginning of the genesis.json, if the JSON looks consistent or if there are any logs?

Can you also try it to export the JSON?
gaiad export --for-zero-height --height=9961097 2> mainnet-genesis.json

I found two bugs regarding the export and validate-genesis commands.

• The export command adds some logs into the genesis file. I opened issue bug(export): genesis.json shows some plain-text logs #1726 to track the bug
• There are a bunch of parameters necessary for the validation missing into the mainnet JSON, as @glnro mentioned in the last comment. Adding these parameters below, the validate-genesis will work:

think we just need to hard code our bank metadata in our initgenesis or export genesis for gaia
