Type Alias ErrorCode

ErrorCode: "VALIDATION" | "NOT_FOUND" | "TEMPLATE" | "CRYPTO" | "INTERNAL"

The error codes an AnzaError can carry. They are the same in the Rust, TypeScript and Python engines (see the Engine Contract).

Code	Raised when
`VALIDATION`	A request or name is malformed: empty route, empty template or slot, a template name with `..`, `\`, NUL or a leading `/`, a missing template root.
`NOT_FOUND`	An unknown page or template, or a fragment outside the `fragments` allowlist. Also unreadable files at load time.
`TEMPLATE`	A template cannot be parsed (unclosed `{{` / `{{{`, empty `{{}}`) or is larger than `maxTemplateBytes`.
`CRYPTO`	A signing key is missing or malformed at setup, key derivation fails, or {@link verifyEnvelope} rejects an envelope.
`INTERNAL`	An unexpected failure inside the engine.
