Thanks for the report.

Can you paste the cargo.toml file contents you are using here?

I'm seeing the same issues with the same development environment:

$ rustup target add x86_unknown-linux-musl
error: toolchain 'nightly-x86_64-apple-darwin' does not contain component 'rust-std' for target 'x86_unknown-linux-musl'; did you mean 'i586-unknown-linux-musl'?

$ rustup default stable
info: using existing install for 'stable-x86_64-apple-darwin'
info: default toolchain set to 'stable-x86_64-apple-darwin'

  stable-x86_64-apple-darwin unchanged - rustc 1.47.0 (18bf6b4f0 2020-10-07)

$ rustup target add x86_unknown-linux-musl
error: toolchain 'stable-x86_64-apple-darwin' does not contain component 'rust-std' for target 'x86_unknown-linux-musl'; did you mean 'i586-unknown-linux-musl'?

$ rustup component add rust-std --toolchain x86_unknown-linux-musl
error: x86_unknown-linux-musl is a custom toolchain

Should I be using:

$ rustup target add i586-unknown-linux-musl

Or will this not work in Lambda?

This issue prompted me to try the above command due to an issue with the Rust version used by the compiler:
