Hey @heyAyushh so I think Steel / Rust Checks fails because solana can't be found.

I use a build script here - https://github.com/Perelyn-sama/program-examples/blob/pda-mint-authority/tokens/pda-mint-authority/steel/program/build.rs to get the .so file of the metadata program, so I can I use it in ProgramTest.

Is there something you can do on the gh actions side to make this work? or should I just add the metadata_program.so to the repo?

I'll also add this check in the build script:

    // Check if Solana is installed
    if let Err(err) = check_solana_installation() {
        println!("cargo:warning=Solana check failed: {}", err);
        return;
    }

to make sure my assumption is right.

I tried reproducing this error with act but it passed locally :(
