Getting Error Jedis connection; nested exception is redis.clients.jedis.exceptions.JedisConnectionEx

[rishikesh bansod]

Hi,

    while running prediction request query to keras-mnist example provided at https://github.com/SeldonIO/seldon-core/tree/master/examples/models/keras_mnist . I am getting following error.  

{"error":"server_error","error_description":"Cannot get Jedis connection; nested exception is redis.clients.jedis.exceptions.JedisConnectionException: Could not get a resource from the pool"}

Traceback (most recent call last):

  File "../../../util/api_tester/api-tester.py", line 202, in <module>

    run(args)

  File "../../../util/api_tester/api-tester.py", line 159, in run

    token = get_token(args)

  File "../../../util/api_tester/api-tester.py", line 136, in get_token

    token =  response.json()["access_token"]

KeyError: 'access_token'

How can I resolve this error?

Thanks, 

Rishikesh
