Cannot initialize IBC connection

[filippos47]

Occuring when trying to connect a wasm testnet with Babylon, both in local deployment and infra.

Error is probably due to outdated Babylon dependency, but nevertheless documenting it:

Thanks for reporting! Yes I believe this will be gone after we bump Babylon dependency. However, the latest Babylon is now a private repo while babylon-relayer is public. To make them work together we either need to run Babylon based on the public repo for infra deployment or maintain a babylon-relayer-private. Thoughts?

I suggest that we maintain a babylon-relayer-private, as much as I don't want to add another private repo on our portfolio 😢
