Not able to import WSDL files

My question: From the Postman latest versions, now we can import wsdl files. But I cannot import wsdl file for my webservice. On import, it gives error “Error while importing WSDL 1.1: Converting circular structure to JSON → starting at object with constructor ‘Object’ | property ‘properties’ → object with constructor ‘Object’ | property ‘OutboundDeliveryExecution’ → object with constructor ‘Object’ | property ‘properties’ → object with constructor ‘Object’ — property ‘properties’ closes the circle”.

Please help.
