@the-frey Hi, I am trying to run the cosmwasm/rust-optimizer container (Intel). However, I am getting this error while running the command:

I think you're using a newer version of the cosmwasm template than the one in our tutorial so the API and commands have changed slightly (as the error seems to suggest that the schema is the 1.1 API, not the 1.0 API from the tutorial)

Oops my bad! I noticed it now. Thanks @the-frey !
