"Action failed: Configure the build" without any specified cause or any change to circle.yml

My builds have started to break for no apparent reason saying only “Action failed: Configure the build”.
My circle.yml has not changed since the last successful build, and it passes the linting anyway. What happened?
Here is the yaml:

machine:
node:
version: 4.4.4
environment:
NODE_VERSIONS: 0.10 0.12 4 5 6 7
RELEASE_BRANCH: master

dependencies:
pre:
- ./scripts/run-ci.sh ./scripts/node-matrix.sh ./scripts/install-node.sh
override:
- exit 0

test:
override:
- ./scripts/run-ci.sh ./scripts/node-matrix.sh ./scripts/prepare.sh ./scripts/lint.sh ./scripts/test-unit.sh ./scripts/test-e2e.sh:
parallel: true

deployment:
release:
branch: master
commands:
- ./scripts/run-ci.sh ./scripts/semantic-release.sh

Here is the build:

Never mind. It was an invalid package json that caused the trouble. Yet it was difficult to figure out without a proper error message

+1, had the same issue

I’m trying my first CircleCI 2.0 build now, and its failing in a similar way. I’m starting with a simplified configuration from the examples, just to get things going. I’ve linted the YAML just to make sure it wasn’t something silly.

Here’s my config:

version: 2
executorType: docker
containerInfo:
  - image: node:latest
stages:
  build:
    workDir: /home/ubuntu/action
    steps:
      - type: checkout
      - type: add-ssh-keys
      - type: shell
        name: Install Dependencies
        command: npm install
      - type: shell
        name: NPM Test
        command: npm test

Is there a status page we should be referring to?

Seemed to be an intermittent failure. My tests are now running again…
