Payload deployment ID is required when payload sealing is co

Error message

Payload deployment ID is required when payload sealing is configured

What it means

When payload sealing is configured (an active key env is present), a non-empty deployment ID is mandatory; it scopes the sealing keys to a specific payload deployment. A missing, empty, or whitespace-only deployment ID is rejected after trimming.

Solutions

1. Set the payload deployment ID in the config to the identifier emitted at payload deployment time.
2. Trim/validate the deployment ID source so an empty/whitespace value is caught before load.
3. If sealing is not intended, remove the active key env configuration instead of leaving deployment ID unset.

Example fix

// before
active_env = "PAYLOAD_SEALING_KEY"
deployment_id = ""   // or omitted

// after
active_env = "PAYLOAD_SEALING_KEY"
deployment_id = "dep-9f3a2c"

if active_env.is_some() && deployment_id.map_or(true, |d| d.trim().is_empty()) {
    panic!("deployment ID is required when payload sealing is configured");
}

fn has_deployment_id(dep: Option<&str>) -> bool { dep.map_or(false, |d| !d.trim().is_empty()) }

match PayloadSealingKeys::load(active, &retired, dep) {
    Err(e) if e.to_string().contains("deployment ID is required") => eprintln!("set the payload deployment ID emitted at deploy time"),
    other => other,
}

When it happens

Trigger: Calling load with active_env = Some(...) but deployment_id = None, or Some(" ") which trims to empty and is filtered out, hitting the ok_or_else arm.

Common situations: New sealing setup where the deployment ID field was never filled in, a value that is only spaces, or an upstream system that stopped supplying the deployment identifier after a redeploy.
