Unknown component date picker?

HI

Having problems with date picker not working.

Adding a date picker into a basic form on a node content npage - works ok in Wappler preview, but in browser it does not work and I am getting this error?

error-date805×615 77.6 KB

It appears to be in the header code on the page.

<!-- Wappler include head-page="layouts/admin_main" jquery_slim_33="cdn" fontawesome_4="cdn" is="dmx-app" id="project_creation" appConnect="local" bootstrap4="cdn" components="{dmxValidator:{},dmxFormatter:{},dmxDatePicker:{}}" moment_2="cdn" -->

Anyone know what might be the issue here?
