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](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API/Using_Fetch) or better send the bar.json file from Node-red to uibuilder and then trigger the draw of the chart )
