Java IllegalStateException: Expected State 'STARTED' but Found 'STOPPED' - Troubleshooting Guide

This error message indicates that a method or operation was attempted on an object or component that was not in the expected state. Specifically, the code expected the object to be in the 'STARTED' state, but it was actually in the 'STOPPED' state.

To resolve this issue, you need to identify the root cause of the unexpected state change. This could be due to an error in the code, incorrect configuration settings, or external factors such as network connectivity issues.

Once you have identified the cause, you can take appropriate steps to correct the issue and ensure that the object or component is in the correct state before attempting any further operations. This may involve restarting the object or resetting its state to the expected value.
