SOAP ERROR

Several times per day the following error is showing up in New Relic:

`

As far as I can tell WC_Shipping_Fedex::residential_address_validation has no option to filter the request detail before it is submitted, so there is no possibility of interference from another plugin. What’s strange is that the WSDL file version and the value for Version.Major are set from the same variable $this->addressvalidationservice_version only a few lines apart, yet the error message would indicate that the two values are different at the time the SOAP request is submitted. We are using the latest version of the plugin, 3.4.10.

I am unable to reproduce the error locally. It appears to happen when customers return to the site root from either /checkout or /cart.

WooCommerce Version 3.3.5
WordPress Version 4.9.6
PHP Version 7.1
php-soap Version 7.1.18-1
