The class description for GoogleVertexAIEmbeddings is incorrect. It's currently described as 'Integration with a chat model', but this class is actually for embeddings. Please update the comment to accurately describe the class, for example: 'Integration with Google Vertex AI for embeddings.'

In the embedQuery method, there's no check to ensure that the data array returned by embedDocuments is not empty before accessing its first element. This could lead to a runtime error if embedDocuments returns an empty array. Consider adding a check and handling the case where no embeddings are returned.

The class GoogleVertexAIEmbeddings has been marked as deprecated, which is good. However, to ensure smooth transition for users, it would be helpful to provide more detailed information in the deprecation notice. Consider adding a brief explanation of why the class is being deprecated and provide a code example of how to use the new import location. This will help users understand the change and quickly update their code.

I noticed that a console.log statement has been added to print the URL method. While this might be helpful for debugging, it's generally not recommended to leave console.log statements in production code. Additionally, this log might expose sensitive information about the project ID, location, and model. Consider removing this console.log statement or replacing it with a more appropriate logging mechanism that respects different environments (development vs. production) and doesn't expose sensitive data.

The current test cases for GoogleVertexAIEmbeddings are a good start, but they could be more comprehensive. Consider adding checks for the following:
- The length of each embedding vector (should be consistent and match the expected dimensionality for the chosen model).
- The range of values in the embeddings (typically between -1 and 1 for normalized embeddings).
- Ensure that different input texts produce different embeddings.
- Test edge cases like empty strings or very long texts.
These additional checks will provide more confidence in the correct functionality of the embeddings.

4-10: Enhance test coverage forembedQuery.The test case for
embedQueryis basic. Consider adding checks for:
- The length of the embedding vector.
- The range of values.
- Edge cases like empty strings or very long texts.
12-29: Enhance test coverage forembedDocuments.The test case for
embedDocumentsis a good start but can be improved by:
- Checking the length of each embedding vector.
- Verifying the range of values.
- Testing with edge cases like empty or very long documents.

Remove or replace console.log for sensitive information.
The console.log statement exposes sensitive information, such as the project ID and model. Consider using a logging mechanism that respects different environments and does not expose sensitive data.

Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

The constructor in GoogleEmbeddings is redundant as it only calls the superclass constructor. Removing it will simplify the code.

Description by Korbit AI
What change is being made?
Move Vertex embeddings to the integration package and deprecate the old imports.
Why are these changes being made?
This change is part of a refactoring effort to better organize the codebase by moving the Vertex embeddings functionality to a dedicated integration package. This improves modularity and maintainability. The old imports are deprecated to guide users towards the new structure.
