Hello Cosmonauts!

I’m new and just started playing with the SDK. I’m trying to run a full node. I followed all the instructions here [https://cosmos.network/docs/getting-started/full-node.html](https://cosmos.network/docs/getting-started/full-node.html) and get the following error:

panic: invalid Bech32 prefix; expected cosmos, got cosmosaccaddr

Any ideas what this is? I might be able to debug myself but don’t want to go down that rabbit hole right now.

Note I’m running on Mac 10:13:6

Here is the full error:

Hey!

Essentially the genesis/application state will be invalid as different Bech32 prefixes are used. See my post [here](https://github.com/cosmos/cosmos-sdk/issues/2651) 👍
