Gentx doesn't work in 4.1.0

[AdityaSripal]

Summary of Bug

Trying to use gentx to start single node testnet fails consistently. There was a single time where I did something different and got the chain to start but have not been able to replicate since. Running through the setup below consistently fails for me when it shouldn't on both Ubuntu and Mac.

Version

4.1.0
commit: 72ced60

Steps to Reproduce

# You can run all of these commands from your home directory
cd $HOME

# Initialize the genesis.json file that will help you to bootstrap the network
gaiad init --chain-id=testing testing

# Create a key to hold your validator account
gaiad keys add validator

# Add that key into the genesis.app_state.accounts array in the genesis file
# NOTE: this command lets you set the number of coins. Make sure this account has some coins
# with the genesis.app_state.staking.params.bond_denom denom, the default is staking
gaiad add-genesis-account $(gaiad keys show validator -a) 1000000000stake,1000000000validatortoken

# Generate the transaction that creates your validator
gaiad gentx validator 100000stake --chain-id=testing

# Add the generated bonding transaction to the genesis file
gaiad collect-gentxs

# Now its safe to start `gaiad`
gaiad start

Output:

I think there might be something pathologically wrong about my setup because this happens for me even for versions 4.0.2 and v3.1.0. Would be good to see if others run into the same issue

[colin-axner]

@AdityaSripal I think you forgot to use the --chain-id flag

I think it needs to be gaiad gentx validator 100000stake --chain-id testing

[colin-axner]

Can you post your exact steps to reproduce?

I get

gaiad gentx validator 100000stake
Error: required flag(s) "chain-id" not set
Usage:
  gaiad gentx [key_name] [amount] [flags]

Which tells me the above steps aren't exact. I ran into this same issue, and I thought using the right chain-id fixed it, but I cannot remember

[AdityaSripal]

Ahh yes I pass in --chain-id=testing

[AdityaSripal]

Tried again and it still fails for me, each time I call rm -rf ~/.gaia in order to start over

[colin-axner]

Ohh, I think I remember now. I think you need to run gaiad unsafe-reset-all. I'll look into why this is

[colin-axner]

I figured it out. You aren't bonding enough of the total supply to start the chain. I think the error is a little misleading.

Once I modified your gentx to use the full genesis account balance and did unsafe-reset-all (otherwise you will be stuck on the old init genesis logic), the chain started.
