getActivePinia()" was called but there was no active Pinia. Did you forget to install pinia?

This error typically occurs when you try to call `getActivePinia()` without having Pinia installed or without having an active Pinia instance. To fix this issue, you need to make sure that Pinia is properly installed and initialized in your project.

Here are a few steps you can follow to resolve this error:

1. Install Pinia: Run the following command in your terminal or command prompt to install Pinia using npm or yarn:

   npm install pinia

or

   yarn add pinia

2. Initialize Pinia: In your main entry file (e.g., `main.js` or `main.ts`), import and initialize Pinia by creating a new instance:

   import { createPinia } from 'pinia';

   const pinia = createPinia();

3. Use the Pinia instance: Make sure to use the `pinia` instance you created to access the Pinia functionalities throughout your application.

By following these steps, you should be able to resolve the error and have an active Pinia instance for your application.
