Describe the bug
I hit a weird issue when using this Softalyer API
https://softlayer-api-python-client.readthedocs.io/en/stable/api/managers/SoftLayer.managers.FileStorageManager/#SoftLayer.manage[…]_modified_volume
When I use it in Dallas(us-south), I can get it work properly.
But when I use it in Paris (eu-fr2), I got this error

>>>fsmgr = SoftLayer.managers.file.FileStorageManager(sl_client)
>>>fsmgr.order_modified_volume(590925122, 2100)
Traceback (most recent call last):
  File "/usr/local/lib/python3.9/site-packages/SoftLayer/transports.py", line 226, in __call__
    result = xmlrpc.client.loads(resp.content)[0][0]
  File "/usr/local/lib/python3.9/xmlrpc/client.py", line 1025, in loads
    return u.close(), u.getmethodname()
  File "/usr/local/lib/python3.9/xmlrpc/client.py", line 662, in close
    raise Fault(**self._stack[0])
xmlrpc.client.Fault: <Fault SoftLayer_Exception_Order_InvalidLocation: 'The location provided for this order is invalid.'>

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.9/site-packages/SoftLayer/managers/storage.py", line 273, in order_modified_volume
    return self.client.call('Product_Order', 'placeOrder', order)

    return self.transport(request)

    raise _ex(ex.faultCode, ex.faultString) from ex
SoftLayer.exceptions.SoftLayerAPIError: SoftLayerAPIError(SoftLayer_Exception_Order_InvalidLocation): The location provided for this order is invalid.
I don't think the API requires any location related parameters.  So not sure how The location provided for this order is invalid comes.

Expected behavior
The API succeeds and return a order result.
