Spring Boot HikariDataSource Initialization Error: Failed to Determine Driver Class

This error indicates that there is an issue with the configuration of the data source used by your application. The error message suggests that the driver class for the data source could not be determined.

To resolve this error, you can try the following steps:

1. Check that the necessary database driver is included in your application's classpath. Make sure that the driver jar file is present in the classpath and that it is the correct version for the database you are using.

2. Verify that the datasource properties are correctly configured in the 'application.properties' or 'application.yml' file. Ensure that the driver class name is specified correctly and that the database URL, username, and password are correct.

3. If you are using a custom data source configuration, ensure that it is correctly implemented and configured. Double-check that the properties are set correctly and that any required dependencies are included.

4. Try updating the version of the database driver being used. It is possible that the version you are using is not compatible with the version of the database you are using.

If none of these steps resolve the issue, you may need to seek assistance from a developer or support team familiar with your application and its dependencies.
