Running the build command for the production-ready build for cw-20 and not only ends with the error:

Building contract in /code ...
   Compiling cw20-base v0.15.1 (/code)
error[E0277]: the trait bound `QueryMsg: QueryResponses` is not satisfied

   = note: this error originates in the macro `write_api` (in Nightly builds, run with -Z macro-backtrace for more info)

It looke like the issue was with:

docker run --rm -v "$(pwd)":/code \
  --mount type=volume,source="$(basename "$(pwd)")_cache",target=/code/target \
  --mount type=volume,source=registry_cache,target=/usr/local/cargo/registry \
  cosmwasm/rust-optimizer-arm64:0.12.6

but running instead:

docker run --rm -v "$(pwd)":/code \
 --mount type=volume,source="$(basename "$(pwd)")_cache",target=/code/target \
 --mount type=volume,source=registry_cache,target=/usr/local/cargo/registry \
 cosmwasm/rust-optimizer-arm64:0.12.8

i.e. using rust-optimizer-arm64:0.12.8 intead of rust-optimizer-arm64:0.12.6 fixes it.
