Hi,

I have set up UPS shipping in the backend, and all my products have weights. Now I am encountering this error when shipping methods dropdown is attempting to get filled...

System.NullReferenceException: Object reference not set to an instance of an object.

its seems that objshippingdetails is nothing and has no weight value, but why is that happening...

Please advise
