从GAE API使用endpointscfg生成Java客户端库时出现HTTP 500错误

Question

I tried to generate java client library using a discovery doc retrieved from my API endpoints (which is running on golang) but failed wit the following message.

endpointscfg.py gen_client_lib java happylaundry.rest.discovery

Traceback (most recent call last):

I tried to use the same command and generated for a very simple program, and it runs without errro. From the syntax or structure of the discovery doc, i can't see anything ran wrong. Do you guys have any idea?

Answer 1

I remove this part from "schema" section from the discovery document, and it works.

"Order": { "id": "Order", "type": "object", "properties": { "addressArea": { "type": "string" }, "addressDistrict": { "type": "string" }, "addressField1": { "type": "string" }, "addressField2": { "type": "string" }, "addressField3": { "type": "string" }, "addressField4": { "type": "string" }, "amountPayable": { "type": "integer", "format": "int32" }, "completed": { "type": "boolean" }, "createdAt": { "type": "string", "format": "date-time" }, "deliveryDate": { "type": "string", "format": "date-time" }, "deliveryTimeslot": { "type": "integer", "format": "int32" }, "id": { "type": "string" }, "pickupDate": { "type": "string", "format": "date-time" }, "pickupDeliveryInstruction": { "type": "string" }, "pickupTimeslot": { "type": "integer", "format": "int32" }, "referenceNumber": { "type": "string" }, "status": { "type": "integer", "format": "int32" }, "－": { "type": "string" } } },
