Resolution Notes

# Action Comments

1

Check system event for underlying exception

The System Event contains an exception field.

Additionally, explore the StateStore logs to determine the underlying issue.

The StateStore is backed by a database, and the exception could have arisen from a number of issues. For example, if the StateStore is underpinned by MongoDB, there could be a connection exception or a authentication exception (not exhaustive list)

2

Remediate the issue

Varies depending on the StateStore DB issue

3

Restart the application

Alternatively, if the issue was transient, you can retry the command that saw the issue arise.
