The source repository for change-emitter 0.1.2 could not be determined

While trying to include change-emitter NPM package in webjars.org it encounters an error:

The source repository for change-emitter 0.1.2 could not be determined but is required to published to Maven Central. This will need to be fixed in the project's package metadata.
If you feel you have reached this failure in error, please file an issue: https://github.com/webjars/webjars/issues

It seems like the package.json does not properly points to the repo.
On the NPM package information page the link to git repository is missing as well.

Check the package.json file for the repository field. The issue is that the metadata is missing or incorrect, preventing automated publishing to Maven Central via webjars.org. Update the repository URL in package.json to point to the correct GitHub repository. Verify the fix by checking the NPM package page shows the repository link.
