Swagger generates a OneOfPaymentResponseDataPaymentMethod and PaymentResponseData model files. In the PaymentResponseData class $swaggerTypes property the Namespace is not applied to payment_method. I have to manually add the Namespace here. Not the author of this but trying to understand what is causing this. Thanks. protected static $swaggerTypes = [ 'payment_type' => '\NameSpace\Model\PaymentType', 'payment_method' => 'OneOfPaymentResponseDataPaymentMethod', 'amount' => 'double', 'billing_first_name' => 'string', 'billing_last_name' => 'string', 'billing_phone' => 'string', 'billing_address' => '\NameSpace\Model\Address', 'notes' => 'string', 'error_message' => 'string' ]; PaymentResponseData: type: object required: - paymentType - paymentMethod - amount - billingFirstName - billingLastName - billingPhone - billingAddress - notes properties: paymentType: $ref: "#/components/schemas/PaymentType" paymentMethod: oneOf: - $ref: "#/components/schemas/CreditCardResponse" - $ref: "#/components/schemas/CreditCardTokenResponse" amount: type: number format: double example: 550.12 billingFirstName: type: string example: John billingLastName: type: string example: Smith billingPhone: type: string example: 800-343-2891 billingAddress: $ref: "#/components/schemas/Address" notes: type: string errorMessage: type: string nullable: true
