Transformers.js embedding failed: ${message}

Error message

Transformers.js embedding failed: ${message}

What it means

Thrown from TransformersEmbeddingService.embed when the ONNX pipeline call fails for a given text; the per-text error surfaces after an embed_error event, and other texts may still embed successfully.

Solutions

1. Inspect the wrapped message; reduce input length if the model rejects oversized inputs.
2. Ensure the pipeline finished initializing before calling embed; await initialization.
3. Retry with a smaller batch to rule out memory pressure in the ONNX runtime.
