## Enable debug mode

The SDK logs everything that happens internally, which can be useful for detecting and diagnosing issues with your integration. Each log receives a severity level, so you can filter only those messages you need.

The severity levels and their respective meanings are:

- **Debug**\
  Step-by-step information useful for debugging.
- **Info**\
  Informational messages that provide additional context or details.
- **Warning**\
  Potential issues that might be problems or might not.
- **Error**\
  Abnormal or unexpected behaviors that need attention.

To enable debug logging, pass the [`debug`](/reference/sdk/vue/api/functions/create-croct#debug-prop) option when initializing the SDK:

**JavaScript**

```js
import {createApp} from 'vue';
import {createCroct} from '@croct/plug-vue';
import App from './App.vue';

const app = createApp(App);

app.use(createCroct({
  appId: 'APPLICATION_ID',
  debug: true,
}));

app.mount('#app');
```

**TypeScript**

```ts
import {createApp} from 'vue';
import {createCroct} from '@croct/plug-vue';
import App from './App.vue';

const app = createApp(App);

app.use(createCroct({
  appId: 'APPLICATION_ID',
  debug: true,
}));

app.mount('#app');
```

Then, opening the browser console should show the logs.

## Check the network requests

Sometimes, the issue is caused by a network request failing, either because of a network issue or a misconfiguration.

You can check the network requests by opening the **Developer Console** in your browser and going to the **Network** tab. Issues with network requests will be highlighted in red.
