It looks like you are trying to use a String value as the argument for a @ManyToOne annotation that is expecting an object of type Country.

To fix this issue, you will need to first ensure that you have a Country object available to use. This object can be obtained by querying the database or by creating a new instance of the Country class and setting its properties.

Once you have a Country object, you can pass it as the argument to the @ManyToOne annotation.

Alternatively, if you are trying to use a String value to represent the Country, you will need to modify your code to first retrieve the Country object from the database or create a new instance of the Country class based on the provided String value. You can then pass the Country object as the argument to the @ManyToOne annotation.

It is important to note that the @ManyToOne annotation expects an object, not a String value.
