/**
 * @description
 * This plugin integrates the [Sentry](https://sentry.io) error tracking & performance monitoring
 * service with your Vendure server. In addition to capturing errors, it also provides built-in
 * support for [tracing](https://docs.sentry.io/product/sentry-basics/concepts/tracing/) as well as
 * enriching your Sentry events with additional context about the request.
 *
 * ## Pre-requisites
 *
 * This plugin depends on access to Sentry, which can be self-hosted or used as a cloud service.
 *
 * If using the hosted SaaS option, you must have a Sentry account and a project set up ([sign up here](https://sentry.io/signup/)). When setting up your project,
 * select the "Node.js" platform and no framework.
 *
 * Once set up, you will be given a [Data Source Name (DSN)](https://docs.sentry.io/product/sentry-basics/concepts/dsn-explainer/)
 * which you will need to provide to the plugin.
 *
 * ## Installation
 *
 * Install this plugin as well as the `@sentry/node` package:
 *
 * ```sh
 * npm install --save \@vendure/sentry-plugin \@sentry/node
 * ```
 *
 * ## Configuration
 *
 * Before using the plugin, you must configure it with the DSN provided by Sentry:
 *
 * ```ts
 * import { VendureConfig } from '\@vendure/core';
 * import { SentryPlugin } from '\@vendure/sentry-plugin';
 *
 * export const config: VendureConfig = {
 *     // ...
 *     plugins: [
 *         // ...
 *         // highlight-start
 *         SentryPlugin.init({
 *             dsn: process.env.SENTRY_DSN,
 *             // Optional configuration
 *             includeErrorTestMutation: true,
 *             enableTracing: true,
 *             // you can also pass in any of the options from \@sentry/node
 *             // for instance:
 *             tracesSampleRate: 1.0,
 *         }),
 *         // highlight-end
 *     ],
 * };
 *```
 *
 * ## Tracing
 *
 * This plugin includes built-in support for [tracing](https://docs.sentry.io/product/sentry-basics/concepts/tracing/), which allows you to see the performance of your
 * GraphQL resolvers in the Sentry dashboard. To enable tracing, set the `enableTracing` option to `true` as shown above.
 *
 * ## Instrumenting your own code
 *
 * You may want to add your own custom spans to your code. To do so, you can use the `Sentry` object
 * just as you would in any Node application. For example:
 *
 * ```ts
 * import * as Sentry from "\@sentry/node";
 *
 * export class MyService {
 *     async myMethod() {
 *          Sentry.setContext('My Custom Context,{
 *              key: 'value',
 *          });
 *     }
 * }
 * ```
 *
 * ## Error test mutation
 *
 * To test whether your Sentry configuration is working correctly, you can set the `includeErrorTestMutation` option to `true`. This will add a mutation to the Admin API
 * which will throw an error of the type specified in the `errorType` argument. For example:
 *
 * ```graphql
 * mutation CreateTestError {
 *     createTestError(errorType: DATABASE_ERROR)
 * }
 * ```
 *
 * You should then be able to see the error in your Sentry dashboard (it may take a couple of minutes to appear).
