The newly released version 0.3.11 of the Node.js library, available on npm and GitHub, introduces a function called handleErrorWithPayloadData to the public API. This addition enhances the library's integration with the Rollbar API, enabling users to report errors with more detail, such as categorizing them as warnings and attaching additional data. This function is particularly useful for customizing error reports and utilizing the extensive capabilities of the Rollbar API, with further examples provided in the documentation for caught exceptions.
