How to remove many excepition tips in console

[liyihongcug]

Errors are below
var vectorTile = new L.vectorGrid.protobuf(vectorLayerUrl, getVectorOptions('name

Google browser said it can't find some pbf file but That can't impact web applicton which run normally.
But whether can Those terrible tip be removed in order to good user experience?
