No 'Test failed, details in $1' message in console log

[darina-techery]

When I run my tests in headless mode, I do not receive any output in my console log, though report is generated.

I have a sample spec with 1 failing test. I launch it using the following command: as-a staging cypress run, where 'staging' is a user in staging env, or CYPRESS_BASE_URL=... cypress run.
In both cases I can see no message 'Test failed, details in $1' in my output. Instead, a file 'failed-exec.json' is generated in the project root folder. It contains the following data:

  "stdout": "",
  "stderr": "/bin/bash: ./on-failed.sh: No such file or directory",
  "code": 127
}

A report file, 'failed-${testname}.json' appears next to it.

I have require('cypress-failed-log'); in my support/index.js and NPM script failed-test in package.json. The cypress-failed-log package is listed under devDependencies in package.json.
Cypress version: 2.1.0
cypress-failed-log: 2.0.0
My tests are running under macOS.
