Dear Mendix Community, We discovered following error when trying to call a Microflow from a Page. We are running on Mendix 9.4.0. Cleaning deployment directory and updating the widgets was not helping. The Debugger on the first action of the microflows will not be triggered by the onclick action. And the mxui.js in the js console is not helping either.. Thanks for your help. Best Regards, Frederik An error occurred while executing an action of RuleMaturityModule.Homepage.container19: Cannot read property 'referenceEntity' of undefined Error: An error occurred while executing an action of RuleMaturityModule.Homepage.container19: Cannot read property 'referenceEntity' of undefined at http://localhost:8080/mxclientsystem/mxui/mxui.js?637654095500657577:73:140039 at we (http://localhost:8080/mxclientsystem/mxui/mxui.js?637654095500657577:31:6501) at i (http://localhost:8080/mxclientsystem/mxui/mxui.js?637654095500657577:31:6402) at w (http://localhost:8080/mxclientsystem/mxui/mxui.js?637654095500657577:73:5772)
