I've errors in the localhost:5600 UI such as:
TypeError: t is undefined. See dev console (F12) and/or server logs for more info.

TypeError: t is undefined
    datasets TimelineBarChart.vue:99
    Lodash 10
    value TimelineBarChart.vue:99
    value TimelineBarChart.vue:45
    VueJS 12
vue.runtime.esm.js:1888:12

The only probably relevant thing that it may contribute to this is I have custom (very simple) categorize which I have to each time export the latest and then import again.

First, is the 404 error in aw-server log related here, and how can I fix the seemingly vu.js icon issue?
Second, is there a better way than export/import the categories (if relevant)
