Vue leaflet loading images section how to avoid due to lack of slice 404 request?-CodePudding

I just contact the GIS soon and slice loaded main code:

 
Let njdronesOptions={
MaxZoom: 21, 
MinZoom: 12, 
ErrorTileUrl: "' 
} 
Let njlayer=L.t ileLayer ('../thSection/nanjing/section/XH1/{z}/{x}/{} y PNG ', njdronesOptions) addTo (enclosing map)

Image slices is the cesiumlab cut out, the original image is complete, no matter how you slice, slice request always call does not exist, at present there are 50 project areas section, page 404 requests a load directly because too much stuck, want to ask next bosses, for this kind of situation is there any way to do?
