Describe the bug

When I run yarn npm audit --recursive / yarn npm audit -R, so with the recursive option enabled I receive the following error:

YN0001: TypeError: le.trim is not a function

Some inspection makes me have a hunch that the dependency @backstage/plugin-scaffolder-backend-module-bitbucket could be the cause. Since the value of le seems to resolve to a boolean value of true and thus true.trim() is not a function.

I've created a minimal reproduction here: https://github.com/RikClaessens/yarn-npm-audit-error

To reproduce

Use the repo here: https://github.com/RikClaessens/yarn-npm-audit-error

Or:

1. In any project, yarn add @backstage/plugin-scaffolder-backend-module-bitbucket.
2. yarn npm audit -AR
