JSON decoding error #2

Closed 2opremio closed 7 years ago

2opremio commented 7 years ago

After deploying the microservices-demo on ECS (with the cloud formation template) and making suer that the Stack finished creating, I proceeded to load-test the deployment with docker run weaveworksdemos/load-test -h host -c 2 -r 1000

It works for the most part, but I continuously get this error:

It seems to succeed for the most part. Here's a longer excerpt:
