@nhtio/adk/batteries/generation/transformers_js/exceptions

Battery-scoped exception constructors for the transformers.js Generation (on-device text→image) adapter.

Remarks

Battery-scoped exception classes for the transformers.js (@huggingface/transformers) Generation adapter, minted via createException from @nhtio/adk/factories. Categories mirror the embeddings/caption transformers.js batteries' E_INVALID_*/E_*_ENGINE_ERROR pair, plus a third E_*_UNSUPPORTED_OPERATION exception (mirroring @nhtio/adk/batteries/vector!E_VECTOR_STORE_UNSUPPORTED_OPERATION's [operation, reason] shape) for edit(), which this engine cannot perform — Janus (DeepSeek MultiModalityCausalLM) only exposes text-conditioned generate_images, no image-conditioned edit/inpaint entry point.

Variables

Variable	Description
E_INVALID_TRANSFORMERS_JS_GENERATION_OPTIONS	Thrown when the resolved adapter options fail validation against transformersJsGenerationOptionsSchema — e.g. a missing/empty model or an unknown option key. Fatal: config bugs fail loud, not at generate time.
E_TRANSFORMERS_JS_GENERATION_ENGINE_ERROR	Thrown when the transformers.js model/processor fail to load (e.g. the @huggingface/transformers peer is not installed), the generate_images call throws, or the result is malformed/empty (no images returned is an engine failure, not a valid empty result). Non-fatal. Printf arg: [detail].
E_TRANSFORMERS_JS_GENERATION_UNSUPPORTED_OPERATION	Thrown when a caller invokes an operation this engine does not support — today, only edit(). Janus (MultiModalityCausalLM.generate_images) is text-conditioned image generation only; there is no image-conditioned edit/inpaint entry point in the installed @huggingface/transformers API surface. Fatal: the caller must not retry an operation the engine structurally cannot perform. Printf args: [operation, reason].
