Got "panic: json: cannot unmarshal object into Go struct field msgCreateValidatorJSON.pubkey of type string"

Hi,
I successfully installed the latest version of gaiad and gaia-cli on my 18.04 box, I followed the instructions to join the testnet however gaiad doesn’t seem to start, I got the following message when starting the daemon:
$ gaiad start I[2019-01-27|00:12:23.823] Starting ABCI with Tendermint module=main panic: json: cannot unmarshal object into Go struct field msgCreateValidatorJSON.pubkey of type string goroutine 1 [running]: github.com/cosmos/cosmos-sdk/cmd/gaia/app.(*GaiaApp).initFromGenesisState(0xc000b10480, 0x1248f00, 0xc000b45800, 0xc000b36cc0, 0xd, 0xc0009ca000, 0x3d9, 0x3d9, 0x0, 0x0, ...) ...

I can’t find anything in the logs. Any idea what could be missing here?
Thanks

Try setting log_level to “*:debug”, and see if you see anything insightful.

I have now more details:

`$ gaiad start

But still no clue where the issue is and how to fix it

This is probably a bug (or at least a desired genesis validation rule); please file an issue on the Cosmos SDK repository with the exact sequence of commands required to reproduce the issue and we’ll take a look.

I was able to move on after resyncing the SDK repository and running $ gaiad unsafe-reset-all
Thanks
