When a policy check fails, Node.js by default will throw an error. It is possible to change the error behavior to one of a few possibilities by defining an “onerror” field in a policy manifest. The following values are available to change the behavior:

    • "exit": will exit the process immediately. No cleanup code will be allowed to run.
    • "log": will log the error at the site of the failure.
    • "throw": will throw a JS error at the site of the failure. This is the default.
