Error: Cannot get the current branch name

[billmoser]

My local builds work fine, but my travis-ci builds give me this error:

jsdoc-examples@1.0.0 gitdown /home/travis/build/billmoser/examples-plugin-jsdoc

This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag --unhandled-rejections=strict (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 1)

there seems to be a parameter called config.defaultBranchName that might be applicable here, but I have no idea how to use it in my README.md

You would typically get this error in a detached HEAD state, or in case you are not in a git directory.

You will need to debug this further to evaluate if either of the above is true. Start by adding git branch to your CI/CD pipeline and see what it prints just before this error.
