@Roznovjak how are you building the runtime? Why do you think that it did not set the env variable?

I'm building it with cargo build --release -p hydradx-runtime --features=metadata-hash.
After the build, echo $RUNTIME_METADATA_HASH is empty.

After the build, echo $RUNTIME_METADATA_HASH is empty.

The env variable is not only set for the wasm-builder in the build process. It will not be set afterwards.

Ah. Thanks.
