You have to not worry about this error this is mongoose warning . Actually Mongoose use inspect() to debug output . they will update it may be before node 12.x . For now it is safe to use this.
Nothing to worry.
Check this info. https://nodejs.org/api/deprecations.html#deprecations_dep0079_custom_inspection_function_on_objects_via_inspect
DEP0079: Custom inspection function on Objects via .inspect()# Type: Runtime
Using a property named inspect on an object to specify a custom inspection function for util.inspect() is deprecated. Use util.inspect.custom instead. For backward compatibility with Node.js prior to version 6.4.0, both may be specified.
If you want more detail, see this . This is under progress. Warning will come in node 10
