[authentication-local] Error: the id property must be set on the entity service for authentication

[Mangatt]

Steps to reproduce

When you combine @feathersjs/authentication-local with custom service (e.g. not with provided one), you'll get this error Error: the 'id' property must be set on the entity service for authentication from verifier.js#81.

I took me quite a while to reverse engineer where is the problem. Appareantly it is talking about users service, not authentication one and setting this.id on custom service makes magically everything working again.

Expected behavior

There should be mention about that in docs or added configuration option for auth plugin.

Actual behavior

It makes you wonder what is going on instead of making you productive.

This will be fixed by Authentication v3 (#1045) where you can explicitly set the entityId in your configuration.

[averri]

@Mangatt and @daffl , could you please provide more information about how to set the entityId? Please post the hooks for the users service.

This has been done in Feathers v4 authentication where entityId can be set in the service configuration. See the migration guide for more information.
