By default the gateway should not return the server stack traces to the Client

[samsja]

Context

When an error is raise on Server side the full stack trace is send by default to the Client. This trace stack could contains sensitive information like the file path and the name of the user which is used to host the service, therefore it is a security issue.

• The normal behavior should be to only return internal error like with a normal http connection.
• Nevertheless the feature is useful for debugging and should be enable when working on debugging mode.

How to reproduce:

server

from jina import DocumentArray, Executor, Flow, requests


class MyExec(Executor):
    @requests
    async def add_text(self, docs: DocumentArray, **kwargs):
        raise Exception('oops')


f = Flow(port=12345).add(uses=MyExec).add(uses=MyExec)

with f:
    f.block()

client

from jina import Client, Document


c = Client(host='grpc://0.0.0.0:12345')
r = c.post('/', Document(), return_responses=True)

print(r[0].status.exception.stacks)
