Cant convert vector element for scores index=0

The error message suggests that there is a problem converting the element at index 0 of the 'scores' vector.

To fix this issue, you can check the type of the element at index 0 and ensure that it can be converted to the desired type. For example, if you are trying to convert the element to an integer but it is a string, you can use a conversion function or method specific to the desired type to convert the element.

If the element cannot be converted due to invalid or incompatible data, you may need to verify the data source or perform additional data cleaning or validation steps before attempting the conversion
