Superseded by the SLF4J structured log events emitted by the SDK (inject a logger via
StreamClientOptions.setLogger). Kept for backward compatibility. Secret headers,
secret body keys, and secret URL query values (api_key/api_secret/
token) are now redacted in its output.
Renamed to Webhook.InvalidWebhookError. Will be removed in the next minor release.
Kept as a subclass so existing catch (WebhookException e) clauses continue to
compile and catch the new class.
