Assertion Failed: The key provided to set must be a string

I have a that passes an ID to the details.js route. This route findRecord my model passing the ID. The payload loads all the data, but when the page finishes loading it comes the error. I didn't find the "key" and i don't have a pokemon.detalhes controller.

Error: Assertion Failed: The key provided to set must be a string, you passed (generated pokemon.detalhes controller).

My Code: adapter.js

import DS from 'ember-data';

    headers: computed(function () {
        return {
            'accept': 'application/json'
        };
    }),

    pathForType(type) {
        return type;
    },
/*
    query(store, b, query) {
        store.serializerFor('pokemon').set('pageSize', query.limit);
        const url = `${this.get('host')}/${this.get('namespace')}/pokemon`;
        console.log(url);
        return this.ajax(url, 'GET', {data: query});
    },
*/
    updateRecord(store, type, snapshot) {
        const data = snapshot.record.serialize();
        const headers = Object.assign({}, this.get('headers'), { "pokemon-edit": true });
        const url = this.buildURL(type.modelName, snapshot.id, snapshot, 'updateRecord');
