Error Instantiating EmbeddingModel with ONNX Model intfloat/multilingual-e5-large

[zelhaddioui]

Describe the issue

I am encountering an error while trying to instantiate the EmbeddingModel using the ONNX model intfloat/multilingual-e5-large. The error message is as follows:

Failed to instantiate [org.springframework.ai.embedding.EmbeddingModel]: Factory method 'embeddingClient' threw exception with message: data did not match any variant of untagged enum PreTokenizerWrapper at line 69 column 3

I am unsure why this error is occurring. Below are the relevant details and configuration:
Configuration

• Model: intfloat/multilingual-e5-large
• Format: ONNX
• Spring Configuration: Using TransformersEmbeddingModel from Spring AI

To reproduce

1. Export the intfloat/multilingual-e5-large model to ONNX format.
2. Configure Spring AI to use the exported ONNX model and tokenizer.
3. Attempt to instantiate the EmbeddingModel.

Urgency

High

Could someone provide guidance on resolving this issue or point out what might be wrong with the configuration?

Please report this to Spring AI. When you do, you should put the full stack trace in as it's hard to tell where the error is without it.
