BUGFIX: Avoid unsupported operand types error
BUGFIX: Avoid unsupported operand types error

Under some circumstances, the session metadata cache might iterate a non-array value and the following logging attempt failing with an unsupported operand type error for the `+` array concatenation. This change works around this error, by checking the `$sessionInfo` to be of type array and assigning a wrapper array otherwise.
