How to get all properties name list in custom module detail page?

[payalpatel]

I have one custom module and I need to get properties name list in this module as a multi-select.

How it’s possible in shopware 6?

Here is my code, please check.

custom-product-detail.html.twig

<sw-entity-multi-select
   :localMode="module.isNew()"
   :label="$t('custom-product.detail.assignPropertyLabel')"
   v-model="module.options">
</sw-entity-multi-select>

custom-product-detail/index.js

import template from './custom-product-detail.html.twig';

const { Component, Mixin } = Shopware;
const { Criteria } = Shopware.Data;
const newLocal = 'custom_product';

Component.register('custom-product-detail', {
    template,

    inject: [
        'repositoryFactory',
    ],

    mixins: [
        Mixin.getByName('notification')
    ],

    metaInfo() {
        return {
            title: this.$createTitle()
        };
    },

    data() {
        return {
            module: null,
            isLoading: false,
            processSuccess: false,
            repository: null,
            repositoryProperties: null,
            properties: []
        };
    },

    created() {
        this.repository = this.repositoryFactory.create(newLocal);

        this.repositoryProperties = this.repositoryFactory.create(property_group);

        this.getModule();
		this.loadEntityData();
    },

    methods: {
        getModule() {
            this.repository.get(this.repositoryProperties, this.$route.params.id, Shopware.Context.api).then((entity) => {
                this.module = entity;
                this.isLoading = false;
            });
        },

        loadEntityData() {
            this.isLoading = true;

            var criteria = new Criteria();
            criteria.addAssociation('options');

            return this.repositoryProperties.search(criteria, Shopware.Context.api).then((result) => {
                this.total = result.total;
                this.properties = result;
                this.isLoading = false;

                return result;
            }).catch(() => {
                this.isLoading = false;
            });
        },

        onClickSave() {
            this.isLoading = true;

            this.repository
                .save(this.module, Shopware.Context.api)
                .then(() => {
                    this.getModule();
                    this.isLoading = false;
                    this.processSuccess = true;
                }).catch((exception) => {
                    this.isLoading = false;
                    this.createNotificationError({
                        title: this.$t('custom-product.detail.error-message'),
                        message: exception
                    });
                });
        },

        saveFinish() {
            this.processSuccess = false;
        }
    }
});

I have tried but I got the below error.
