[HPM] Error occurred while proxying request

[LeungYu]

A problem occurred while using http-proxy-middleware:

[HPM] Error occurred while proxying request test.oa.py:10000/queue/nextPending to http://test.oa.io:16666/ [ENOENT] (https://nodejs.org/api/errors.html#errors_common_system_errors)

I am not sure how it happenned, it didn't give out more information. I tried to access the link above by chrome when nodejs give out these errors, it can work.
