Error message

%w

What it means

The `argoexec init` cobra command (which loads input artifacts before the main container runs) wraps any error returned by loadArtifacts with fmt.Errorf("%w", err). This is a pure pass-through wrapper: the message adds no text, and the wrapped cause is preserved for errors.Is/errors.As inspection. The real failure originates in artifact loading (storage backend auth, missing artifact, bad S3/GCS/Git config, etc.).

Solutions

1. Read the wrapped cause printed after this error — it identifies the actual artifact-loading failure
2. Verify artifact repository credentials and endpoint configuration in the controller configmap
3. Confirm the input artifact's key/path exists in the storage backend
4. Test egress/network connectivity from the workflow pod to the artifact storage endpoint

// the wrapper preserves the cause via %w; unwrap for specifics
if err := loadArtifacts(ctx); err != nil {
    return fmt.Errorf("%w", err) // at call site: errors.Unwrap / errors.As to classify
}

When it happens

Trigger: Running `argoexec init` (legacy pod layout) where loadArtifacts fails — e.g. an input artifact cannot be downloaded because of missing credentials, an unreachable storage endpoint, or a nonexistent artifact key.

Common situations: Misconfigured artifact repository credentials in workflow-controller-configmap; deleted/expired S3 objects; network egress blocked from workflow pods; typo in an artifact's key/path.
