DPoPInitError

Raised during client construction when DPoP (Demonstrating Proof-of-Possession) key initialization fails — typically because the browser does not expose a usable SubtleCrypto (insecure origin, very old browser) or persistent storage is unavailable for the key material. The error is fatal: a SignalWire instance that cannot initialize DPoP cannot authenticate.
