# Missing plugin

Learn how to configure the Croct plugin.

If you try to use the [`useCroct`](/reference/sdk/vue/api/composables/use-croct) composable without installing the Croct plugin, you will see the error below:

> **Error**
>
> `useCroct()` requires the Croct plugin to be installed.

This indicates that the SDK is not properly initialized. To resolve this issue, follow the steps for [initializing the SDK](/reference/sdk/vue/manual-installation#initialize).
