Troubleshooting

Since Shuttle v0.18.0, protoc is no longer required to use Shuttle. If you encounter the above error, we recommend you upgrade to the latest version of cargo-shuttle and other Shuttle crates.

If you’ve recently updated Shuttle, in order to get your project back up, you need to run: cargo shuttle project restart and everything should be back in working order.

There’s a known bug with arm64 because of the openssl crates being built for x86, rather than arm64. In order to get around that issue, you can either run:

cargo install --features vendored-openssl cargo-shuttle

or install it via binary:

cargo binstall cargo-shuttle

CustomError is an alias for anyhow::Error, the simplest way to output a relevant message here is by using anyhow::Context like this:

pool.execute(include_str!("../schema.sql"))
    .await
    .context("failed to run migrations")?;

Add shuttle-secrets to the dependencies for your service, and add a Secrets.toml to the root of your project with the secrets you’d like to store. Make sure to add Secrets*.toml to your .gitignore to omit your secrets from version control.

Next, pass #[shuttle_secrets::Secrets] secret_store: SecretStore as an argument to your shuttle_runtime::main function. SecretStore::get can now be called to retrieve your API keys and other secrets at runtime.
