Can I please get some help with the error below I have been researching and could not find a solution? I am using amazon AWS for aurora MySQL and already downloaded and set up the driver still running into issues. Any guidance will help me a lot. Thanks in advance.

Welcome to the Liquibase Community, @pkomirishetty - and thanks for posting your question.

I’ve run into a similar issue before. Are you including the driver path in your liquibase.properties file?

If you have already resolved this issue, please drop a line and let us know how you did it. Maybe it’ll help someone else in the future!

Kindly,
