  1. The error message “Member must satisfy enum value set: [LTL, SP]” when using the Amazon SP-API in Python is indicating that the value provided for the “transport_type” parameter is not valid. The transport_type parameter is used to specify the type of transport being used for the shipment.

    The Amazon SP-API only supports two transport types: “LTL” (less-than-truckload) and “SP” (small parcel). So, if you’re seeing this error, it’s likely because the value you’re passing for the “transport_type” parameter is not one of these two options.

    Here are a few things you can try to fix this error:

    • Verify that you are passing the correct value for the “transport_type” parameter. Double-check that you are using “LTL” or “SP” as the value.
    • If you are passing a variable to the “transport_type” parameter, make sure that the variable is set to “LTL” or “SP”.
    • If you are using a library to interact with the Amazon SP-API, make sure that the library is correctly handling the “transport_type” parameter.
    • If the problem persists, it is recommended to check the documentation of the Amazon SP-API and the library you are using, to make sure you are following the correct format for the transport_type parameter.

    In summary, this error occurs when the value passed for the transport_type parameter is not a valid option, you should make sure you are passing “LTL” or “SP” as the value for transport_type, or that the variable you are passing is set to one of these two options.

    The error message “1 validation error detected: Value ” at ‘shipmentType’ failed to satisfy constraint: Member must satisfy enum value set: [LTL, SP]” is indicating that the value provided for the “shipmentType” parameter is not valid. The shipmentType parameter is used to specify the type of shipment being used for the update_transport_information call.

    The Amazon SP-API only supports two shipment types: “LTL” (less-than-truckload) and “SP” (small parcel). The error message is indicating that the value you’re passing for the “shipmentType” parameter is empty, which is not one of the two options.

    Here are a few things you can try to fix this error:

    • Verify that you are passing the correct value for the “shipmentType” parameter. Double-check that you are using “LTL” or “SP” as the value.
    • Check that the value being passed to the “shipmentType” parameter is not an empty string or null.
    • If you are passing a variable to the “shipmentType” parameter, make sure that the variable is set to “LTL” or “SP”.
