Suds throwing exception on "type not found"

We are using SUDS v1.1.1 and recently starting getting a "Type not found" exception as the response to a request contains a field not in the wsdl. I tried initializing the client as follows but the exception is still occurring:

client = Client(spec_path, faults=False)
client.set_options(allowUnknownMessageParts=True, extraArgumentErrors=False)

Is there any other way to get suds to ignore the unknown field without throwing an exception please?

Solution

Could you provide more details (code) about your issue? I was also wondering if you've tried using a custom plugin to bypass the problem, something like:


class IgnoreUnknownFieldsPlugin(MessagePlugin):
    def unmarshalled(self, context):
        # Remove unknown elements before SUDS processes them
        if hasattr(context.reply, 'children'):
            known_elements = [el for el in context.reply.children if el.name in context.reply.__metadata__.sxtype.rawchildren]
            context.reply.children = known_elements

client = Client(spec_path, plugins=[IgnoreUnknownFieldsPlugin()], faults=False)

UPDATE:

The issue occurs because the response contains a payment method type (capitecPay) with an accountNumber field that isn't defined in the WSDL schema, so we will update the plugin to handle paymentMethodsUsed array with unknown types.


class PayUResponseFixPlugin(MessagePlugin):
    def unmarshalled(self, context):
        # Handle paymentMethodsUsed array with unknown types
        if hasattr(context.reply, 'paymentMethodsUsed'):
            for payment_method in context.reply.paymentMethodsUsed:
                # Skip validation for unknown payment method types
                if not hasattr(payment_method, '__metadata__'):
                    # Copy metadata from parent to make it valid
                    payment_method.__metadata__ = context.reply.__metadata__
        
        # Original handling for other unknown elements
        if hasattr(context.reply, 'children'):
            known_elements = [el for el in context.reply.children 
                            if el.name in context.reply.__metadata__.sxtype.rawchildren]
            context.reply.children = known_elements
            
        return context.reply

client = Client(
    spec_path,
    plugins=[PayUResponseFixPlugin()],
    faults=False,
    allowUnknownMessageParts=True
)`
