The error message you are seeing—1 validation error for MarketplacePluginDeclaration\nmodel.position.text_embedding\n Input should be a valid list [type=list_type, input_value=None, input_type=NoneType]—indicates that Dify expects the field model.position.text_embedding to be a list, but it is currently set to None or missing in your DSL file.

This is not a general version compatibility issue with Dify 1.4.0, but rather a problem with the structure or content of your DSL file. The Dify codebase expects certain fields (like model.position.text_embedding) to be lists, even if they are empty. If this field is omitted or set to null/None, validation will fail with the error you encountered. The relevant code expects a list for this field and will not accept None as a valid value (source).

How to resolve:

• Check your DSL file for any section related to model.position.text_embedding.
• If you do not need to specify any embeddings, explicitly set it as an empty list:

  model:
    position:
      text_embedding: []

• If you do need to specify embeddings, provide them as a list:

  model:
    position:
      text_embedding:
        - embedding_model_1
        - embedding_model_2

• Make sure you are not leaving this field as null, None, or omitting it entirely if the schema expects it.

If you are not directly specifying this field in your DSL, it is possible that a plugin or template you are using is generating an incomplete or incompatible manifest. In that case, check the source of your DSL or plugin manifest and ensure it aligns with the expected schema.

There are known compatibility issues with Dify 1.4.0 and some plugins, but those are unrelated to this specific validation error (source).

If you update your DSL as described and still encounter issues, please share the relevant section of your DSL file that defines the model or position fields for further troubleshooting.
