Fixed by setting node version to 11.0.0 in .travis.yml:

language: node_js
node_js:
  - "v11.0.0"
after_success: npm run coverage

It worked when I switched back to node LTS(10.15.0)

Looks like this issue related to this one:
istanbuljs/nyc#973

Same issue with Node.js v12.0 since this was never fixed.

Since this library doesn't seem to be supported anymore I fix a bunch of things on a fork if you want to check it out and are still pulling the library into your packages: https://github.com/jtwebman/coveralls-next
