Describe the bug
It looks like Redis-backed queues are no longer listened to once a list is empty (hence deleted from Redis, since it has no concept of an empty list).
fission function log -f --name producer
fission function log -f --name consumer
Execute:
fission function test --name producer
fission function test --name producer
fission function test --name producer
fission function test --name producer
The producer function log should now show the messages being produced.
Now the consumer function log should show the messages being consumed.
Let's add some more messages:
fission function test --name producer
fission function test --name producer
fission function test --name producer
fission function test --name producer
The logs should show the messages being produced, but NO message is consumed.
Deleting and recreating the trigger fixes the issue: fission mqtrigger delete --name redisbug
Expected result
The messaged should be consumed even after the Redis list is emptied.
Actual result
No messages are further consumed.

To Reproduce
Pre-requirements:
Create a

script:Create a
consumer.py
script:Test setup:
On two different shells start log observers:
Execute:
The producer function log should now show the messages being produced.
Let's create a trigger to consume the messages:
Now the consumer function log should show the messages being consumed.
