Caldera UI Does Not Display New Results After Restart

[HackerFerret]

Describe the bug
I encountered an issue where operations and agents disappear from the Caldera UI after a restart, even though the execution results are stored in caldera/data/results/

To Reproduce
Steps to reproduce the behavior:

1. Successfully deploy an agent and execute an operation (confirmed that results are displayed in the UI).
2. Restart Caldera.
3. Upon restart, the agent and operation from that day are no longer visible in the UI.
4. Check caldera/data/results/ and confirm that the execution results exist.

Expected behavior
After restarting Caldera, the UI should still display the operations and agents, as long as the execution results exist in data/results/.

Desktop (please complete the following information):

• OS: Ubuntu
• Browser: Chrome/Firefox
• Version 4.2.0

Additional context
Troubleshooting Attempts which failed:
• Changed file ownership and permissions of data/results/. (via chown & chmod commands)
• Modified system and file timestamps. (since we thought it might be a new bug recently)
• Attempted to overwrite data/results from a previously successful operation with our new result. (since we thought it might be a bug which the Operation ID couldn't link to the new results)

p.s. We deleted all data in data/results/, but Caldera still displayed old results, suggesting it might not be reading from data/results/.

Request for Help:
Is there another directory or database where Caldera stores operation data? How can we ensure that previously executed operations are properly loaded after a restart?
