Building a Rust application on GitHub Actions gives me "error: UnknownOperatingSystem"

Question

I'm building a Rust application with Cargo Lambda that will be deployed on AWS. The application is built using GitHub Actions for x86 architecture and doing the deployment as well in the workflow.

However I encounter a strange issue when building the Rust application on GitHub Actions.

Locally it builds for ARM64 and it works without any issue. Only on GitHub Actions it throws me an exit status.

Cargo.toml:

[package]
name = "lambda-api"
version = "0.1.0"
edition = "2021"
rust-version = "1.76"

[dependencies]
lambda_http = "0.10.0"
lambda_runtime = "0.10.0"
tokio = { version = "1", features = ["full"] }
tracing = { version = "0.1", features = ["log"] }
tracing-subscriber = { version = "0.3", default-features = false, features = ["env-filter", "fmt"] }
serde = { version = "1.0.196", features = ["derive"] }
reqwest = { version = "0.11", features = ["json"] }
openssl-sys = "0.9"
openssl = { version = "0.10", features = ["vendored"], resolver = "1" }
serde_json = "1.0.113"
base64 = "0.22.0"
log = "0.4.20"
chrono = "0.4"

What I have tried (and didn't help):

• Adding features = ["vendored"] in the openssl dependency definition in Cargo.toml
• Installing dependencies manually in the workflow for libssl-dev and pkg-config using sudo apt-get update && sudo apt-get install -y libssl-dev pkg-config
• Changed ubuntu-latest to ubuntu-20.04
• Manually added the --target flag in the build process for x86_64-unknown-linux-gnu
• Added the dependency openssl-sys = "0.9" in Cargo.toml
• Added:

[target.x86_64-unknown-linux-gnu]
linker = "x86_64-linux-gnu-gcc"

Nothing seems to work. I have exhausted everything I possibly can think of testing to make this work. Any ideas?
