The issue
strong-soap has strong-globalize as a dependency, which has yamljs as a dependency, which has an outdated glob (v7) as a dependency, which finally has inflight as a dependency.
Inflight is a deprecated with the author message
This module is not supported, and leaks memory. Do not use it. Check out lru-cache if you want a good and tested way to coalesce async requests by a key value, which is much more comprehensive and powerful.
This dependency tree should be resolved to avoid using a deprecated dependency.
