If you filter or if you click Reports > Report Resources but there are none, you get the message "TypeError: this.getCheckboxFromTR(_44) is undefined".

Alternatively, click OK to continue and ignore the message. To avoid the error because there are no report resources, create one: Reports > Report Resources > Create Resource.
