This error message indicates that the method similarity_search_with_score() was called with an invalid parameter name include_metadata. This could be because the method does not have a parameter with that name, or because the method is using a different keyword argument name.
To resolve this issue, you can check the documentation of the method to see what parameters it accepts and use the correct parameter names when calling the method. Alternatively, you can modify the method to accept the include_metadata parameter if it is required.
