When testing out my app the widget i'm using to do what i need is failing to render This is the error in the console, now i am far from smart enough to understand this, so any help would be appreciated :) Cannot read properties of undefined (reading 'endsWith') TypeError: Cannot read properties of undefined (reading 'endsWith') at SchedulerData.isContentViewResponsive (http://localhost:8080/widgets/mendix/reactbigscheduler/ReactBigScheduler.js?638512034205515508:46055:33) at SchedulerData.getContentCellWidth (http://localhost:8080/widgets/mendix/reactbigscheduler/ReactBigScheduler.js?638512034205515508:46074:19) at SchedulerData.getContentTableWidth (http://localhost:8080/widgets/mendix/reactbigscheduler/ReactBigScheduler.js?638512034205515508:46078:41) at SchedulerData.getResourceTableWidth (http://localhost:8080/widgets/mendix/reactbigscheduler/ReactBigScheduler.js?638512034205515508:46067:48) at Scheduler.render (http://localhost:8080/widgets/mendix/reactbigscheduler/ReactBigScheduler.js?638512034205515508:47081:48) at As (http://localhost:8080/mxclientsystem/mxui/mxui.js?638512034205515508:29:77427) at ks (http://localhost:8080/mxclientsystem/mxui/mxui.js?638512034205515508:29:77225) at Cc (http://localhost:8080/mxclientsystem/mxui/mxui.js?638512034205515508:29:120560) at wl (http://localhost:8080/mxclientsystem/mxui/mxui.js?638512034205515508:29:108763) at bl (http://localhost:8080/mxclientsystem/mxui/mxui.js?638512034205515508:29:108691) It also shows this error mark on the widget, so is it just that the widget might be outdated or just a visual theirs something wrong still, even though i have no errors? Thanks for any responses!
