What causes "authenticated redis settings failed validation" in juspay/hyperswitch?

Set all required authenticated-Redis env vars correctly (host, port, username/password) before running tests

authenticated redis settings failed validation

Error message

authenticated redis settings failed validation

What it means

`get_auth_pool_or_skip` loads authenticated Redis settings from environment variables and calls `.validate().expect("authenticated redis settings failed validation")`. A panic means the env-derived RedisConfig failed validation (missing/invalid host, port, credentials, etc.).

Solutions

Set all required authenticated-Redis env vars correctly (host, port, username/password) before running tests
Unset the auth env vars entirely so the test skips via auth_settings_from_env() => None
Run settings.validate() manually or print the validation error to see which field is wrong

Example fix

// before
.expect("authenticated redis settings failed validation");
// after
.unwrap_or_else(|e| panic!("authenticated redis settings failed validation: {e:?}; check REDIS_* env vars"));

Defensive patterns

Strategy: validation

Validate before calling

let settings = match auth_settings_from_env() { Some(s) => s, None => return None };
if settings.host.is_empty() || settings.port == 0 { eprintln!("REDIS_* env incomplete"); return None; }

Type guard

fn auth_env_complete() -> bool {
    ["REDIS_HOST", "REDIS_PORT"].iter().all(|k| std::env::var(k).map(|v| !v.is_empty()).unwrap_or(false))
}

Try / catch

settings.validate().unwrap_or_else(|e| panic!("authenticated redis settings failed validation: {e:?}"))

Prevention

Validate REDIS_* env vars before running integration tests
Unset auth env vars to trigger the skip path when no authed Redis is available
Print field-level validation errors instead of bare expects

When it happens

Trigger: Running the integration tests with auth-related env vars set (so auth_settings_from_env returns Some) but with invalid or incomplete values — e.g. bad host, non-numeric/0 port, missing password for an authenticated pool.

Common situations: CI or local runs where REDIS_* env vars are partially set or point at a wrong host; secret not exported; TLS/cluster options mismatched.

Authentication and authorization failures — expired tokens, bad credentials, and missing scopes.
