MapImageLayer how to force ?blankTile=true

[TonyCollins]

Hi, I can see the API making calls to cached services like this:

https://serverurl/arcgis/rest/services/basemaps/basemapname/MapServer/tile/0/58/84?blankTile=false 

Is there anyway I can get the API to use blankTile=true which returns the defined blank tile rather than 404 errors in the application?

Thanks for any help

Should be possible with RequestInterceptor. API Reference: config | ArcGIS API for JavaScript 4.14
