Answer 1

Your issue seems to be that ShippingWeight is invalid.
Their spec sheet says
"ShippingWeight": {
"type": "number",
"title": "Shipping Weight (lbs)",
"minimum": 0,
"maximum": 10000000000000000,
"exclusiveMaximum": false,
"multipleOf": 0.001
},
You need to replace ShippingWeight": "1LB", with ShippingWeight": "1",
Also you don't need to send additionalOfferAttributes if its going to be empty, it is not required.
