Rate Request for Shipment with No Dimensions Defaulting Dimensions to 1 Returning Incorrect Rates.

When rate request is sent for a shipment of sizeable weight but no dimensions, the rates returned are incorrect, extremely low.  The request is sent with default values of 1 in the Length, Width, and Height parameters.
When the Height, Length, and Width are set to zero, or left off completely, The correct rates are returned.

Which is incorrect

When I send request with Zeroes or leave the dimensions off altogether, I get the correct amount compared to Stamps web site.

        </sws:Rate>

Returns

               <InsuredValue>207.32</InsuredValue>
               <DimWeighting>N</DimWeighting>

This amount matches Stamps.com web user interface.

Can the plugin be modified to not send any dimensions if all product dimensions equal zero?

Thanks

Upgrade the plugin. I fixed it.

Leaving the dimensions off doesn't work as planned.  Without the dimensions present, the API returned very high shipping rates.  The request:

     <Rate>
        <FromZIPCode>46898</FromZIPCode>
        <ToZIPCode>97132</ToZIPCode>
        <ToCountry>US</ToCountry>
        <WeightLb>15.4359</WeightLb>
        <PackageType>Oversized Package</PackageType>
        <ShipDate>2023-10-12</ShipDate>
        <InsuredValue>207.3870</InsuredValue>

          <InsuredValue>207.3870</InsuredValue>
          <DimWeighting>N</DimWeighting>

The amount should be around 26.04.

Would it be possible to update the plug-in to send zeroes in the dimensions if all items dimensions equal zero?

Thanks

Done, Upgrade the plugin and try the new release.
