Duplicate module

modules => duplicate <name> ...
you have a module trying to load over another...

henri exposes every module as henri.<name>, so module names must be unique. This error stops the boot when:

  • two modules declare the same name, or
  • a module’s name collides with an existing property of the henri instance (config, pen, model, router, utils, validator, …).

The two log lines before the error give the file and line where each module was registered.

Fix

Section titled “Fix”

Rename one of the modules, or make sure you only call henri.modules.add() once per module. If the collision comes from a package you installed, check that you are not adding the same package twice, for example once from your code and once from a plugin.

See Under the hood for how modules are registered.
