ValidationError: beforeSerialize is not allowed

I'm seeing this error when try to set up a composite id:
ValidationError: beforeSerialize is not allowed

Here's my code to register the types. Note that I am not getting an error to serialize the other relationship locationGoals, which doesn't use beforeSerialize():

      serializer.register('client', {
        id: 'id',
        relationships: {
          alertingAccesses: { type: 'alerting-accesses' },
          locationGoals: { type: 'location-goals' },
        },
      });

      serializer.register('alerting-accesses', {
        beforeSerialize: (data) => {
          return { ...data, id: `${data.realtimeUserId}_${data.clientId}` };
        },
      });

      serializer.register('location-goals', {
        id: 'id',
      });

I've used beforeSerialize() on other occasions without running into this error, so I'm not sure why it's happening here.

json-api-serializer version: 2.5.0

ValidationError comes from the joi package which was used on version lower than 2.0.0.
As of 2.0.0 it no longer uses joi, so you shouldn't get this error.

Please check your version of json-api-serializer

It looks like I had a stale version of this package in my node_modules folder because my package.json has this in it:

I manually removed the package and ran npm install, and everything appears to be working now. Thanks!
