Getting an error while

reports
Assets for Release v14.7.0 don’t exist
This message shows up when frappe’s hosted server doesn’t contain the built JS files for your version of Frappe.
It can be safely ignored.
We have stopped shipping assets for v14 for a while now. Since esbuild builds them in about the same time it takes to download them from internet 
Since any other non-frappe app anyway requires this, it doesn’t help much. Still if there’s something I am missing let us know.
