Shippo error: "{"parcel": ["This field is required."]}"

This error happens when Shippo's API in your account is not up to date. Return Magic uses the latest Shippo API.

Here is how to update the API versioning:

1. Go to the Settings > API section of your Shippo dashboard
2. Under "Versioning", click on "Upgrade available"

Once it is updated, you should be able to retry your label from your Return Magic dashboard and everything should work well!
