Function CleanInitError

cli/internal/platform/inject.go:554–560

CleanInitError turns the gRPC-wrapped plugin-init error from the platform destination into a human-readable message: it unwraps the gRPC status (drops the "rpc error: code = ... desc =" prefix) and strips the plugin-sdk wrapper prefixes, leaving the destination's own message (e.g. the platform's 422

(err error)

// Scope this to the platform destination (see IsInjectedDestination) — the
// stripped prefixes are specific to that plugin's init path.
func CleanInitError(err error) string {
	msg := status.Convert(err).Message()
	for _, prefix := range []string{"failed to init plugin: ", "failed to initialize client: "} {
		msg = strings.TrimPrefix(msg, prefix)
	}
	return msg
}
