Struggling with filtering by age

[markjessell]

Hi I also posted this in TerriaJS, not sure which is hte right place so feel free to delete from one or the other...

Hi I am running Terria on:

Debian 10 / buster
Latest Terria from github (as of 20/5/2022)
GeoServer Version 2.19.4
node.js version 16.15.0

and I want to display a wms layer of dated points from geoserver with time filtering. The temporal filtering in QGIS is happy with the shapefile version of the data, so I assume I have misunderstoood something in the simple.json description of to how to activate it, or that this option isn't available for vector data? The simple.json code is as follows:

{
"type": "wms",
"name": "SAXI geochron database clipped time aware",
"url": "http://13.211.217.129:8080/geoserver/loop/wms",
"layers":"test_age_date",
"timeFilterPropertyName":"age_date",
"startTime":"1500",
"stopTime":"2500",
"dateFormat":"yyyy",
"initialTimeSource":"start"
},
The layer loads fine, but when I click on the Play icon, the whole window goes white. If I try to manually scroll through time all the points show all the time.

All suggestions gratefully accepted.
