Possibly incorrect operand: “index” or “-1”

      if (index === -1 && $ctrl.pagerConfig && $ctrl.pagerConfig.currentPage !== 1) {
        return $ctrl.onPageChange($ctrl.pagerConfig.currentPage - 1).then(() => {
          const prevIssue = $ctrl.issues[$ctrl.issues.length - 1];

if change -1 to (-1) it will not show the error message. Looks like the problem in - sign

      if (index === (-1) && $ctrl.pagerConfig && $ctrl.pagerConfig.currentPage !== 1) {
        return $ctrl.onPageChange($ctrl.pagerConfig.currentPage - 1).then(() => {
          const prevIssue = $ctrl.issues[$ctrl.issues.length - 1];
          prevIssue && $ctrl.selection.focusIssue(prevIssue);

I've had a similar issue as well. As you can see some the details in the screenshot. The type of event.entity.tier is number. As you mention above, wrapping 0 in parenthesis eliminates the error message.

In my case, it looks like the plugin thinks that the LHS could possibly be undefined (even though the source type supports neither undefined nor null. Adding a null coalesce as below also prevents the error from appearing.

if ((event.entity.tier ?? 0) > 0) {
