GAE Cloud Endpoints API Explorer停止工作

Question

Out of the blue, the API explorer (localhost:8080/_ah/api/explorer) stopped working. This is the message 'goapp serve' gives:

My app (localhost:8080) does not work either, with the same problem.

Answer 1

I was passing a map in the response of a service, and it did not like that. Only slices and structs are allowed.
