Market Connect App Error

I've been tring to connect to an ebay agent for over 2 hours to fix an issue that apps team at market connect said I need to contact ebay for but it keeps saying agent connect error. Is there any

other way to contact ebat tech support.

This is the error I get

Thank you for your patience. I have tried republishing the product but still eBay is returning this error : Input data for tag <Item.ShippingPackageDetails.WeightMajor> is invalid or missing. Please check API documentation

 

Kindly contact eBay seller support and provide them the error message above. Because when we check with our team, the data that they are asking for is already filled out.
