Hey @Mushthak007! I'm here to help you with any bugs or questions you have. I'm a bot that can assist with problem-solving, answer your queries, and guide you on becoming a contributor. Let's tackle this issue together!

The error "TypeError: data.map is not a function (it is undefined)" suggests that the data prop being passed to the react-native-reanimated-carousel component is undefined. This prop is expected to be an array, as it is used to define the carousel items [1][2].

To resolve this issue, ensure that the data prop is properly initialized and passed as an array. Here's a quick checklist:

  1. Initialize the Data: Make sure that the data variable is initialized as an array before passing it to the carousel component. For example:

    const data = [/* your data items here */];
  2. Check Data Source: Verify that the data source you are using to populate the data array is correctly fetching or generating the data.

  3. Conditional Rendering: If the data is being fetched asynchronously, ensure that the component only attempts to render the carousel once the data is available. You can use conditional rendering to achieve this:

    {data && data.length > 0 && (
      <Carousel data={data} /* other props */ />
    )}

By ensuring the data prop is correctly defined and passed, you should be able to resolve the error.

u should parse to string and convert into array manually before passing data into component
