Uibuilder error 404 (not found)

[UnborN]

"GET http://localhost:1880/chart_vega_vue/ 404 (Not Found)"

ok .. just confirming because in the error you mentioned, you were possibly trying to load from the chart_vega_vue path that doesnt seem to exist .. so double check.

also what do you expect to happen with this line ?
const vlJson = "bar.json"
read and load the bar.json file ?
(look into using Fetch or better send the bar.json file from Node-red to uibuilder and then trigger the draw of the chart )
