TypeScript Logging and Errors

Reference for @band-ai/sdk 1.0.0.

Logger	Import	Output
`NoopLogger`	`@band-ai/sdk/core`	Nothing; the default
`ConsoleLogger`	`@band-ai/sdk/core`	`console.debug`, `console.info`, `console.warn`; errors to stderr
`StderrLogger`	`@band-ai/sdk/core`	Every level to stderr, for processes whose stdout carries a protocol

A Logger is any object with debug, info, warn and error methods of type (message: string, context?: Record<string, unknown>) => void.

Errors

Exported from @band-ai/sdk/core. All extend BandSdkError.

Error	Raised when
`ValidationError`	Configuration is missing or invalid, including the config loaders’ errors
`RuntimeStateError`	A lifecycle call is illegal in the current state, such as `start()` while `stop()` runs
`UnsupportedFeatureError`	An adapter’s optional peer package is missing, a tool is called whose capability is turned off, or the REST client does not provide an operation
`TransportError`	A transport operation fails
`RecoverableTurnError`	A failure confined to one turn: that message is marked failed, and the room and every other room keep running. Any other error from an adapter stops the runtime

Platform HTTP errors, such as UnauthorizedError for a 401, come from the generated REST client and carry the status code and response body.
