I'll create a module that allows you to upload a .txt or .csv file containing brand names, fetch their logos from the web, and display them in a visual grid system. Here's a comprehensive solution using Next.js and React:

This implementation creates a module that allows users to upload a .txt or .csv file containing brand names. The system then fetches logos for these brands from Unsplash and displays them in a responsive grid.

Here's a breakdown of the components and their functions:

1. parseFile.ts: Utility function to parse the uploaded file and extract brand names.
2. fetchLogo.ts: Utility function to fetch a logo for a given brand name using the Unsplash API.
3. actions.ts: Server action to process the uploaded file and fetch logos for each brand.
4. FileUploadForm.tsx: Client component for file upload and processing.
5. LogoGrid.tsx: Component to display the fetched logos in a grid layout.
6. page.tsx: Main page component that combines the file upload form and logo grid.

To use this module, you'll need to:

1. Set up an Unsplash developer account and get an access key.
2. Add the Unsplash access key to your environment variables (UNSPLASH_ACCESS_KEY).
3. Run the application and upload a .txt or .csv file with brand names (one per line).

The system will then fetch logos for the brands and display them in a responsive grid. Note that this implementation uses Unsplash for demo purposes. In a production environment, you might want to use a more specialized logo API or implement a more robust logo fetching mechanism.

I understand that you're encountering an error when trying to fetch the logo for "HLX Touristik". Let's revise the code to address this issue and make it more robust.

Let's revise the code to address this error:

These changes should address the error you encountered. Here's a summary of the modifications:

1. We've updated the fetchLogo function to try two different APIs (Unsplash and Clearbit) to fetch logos. If both fail, it returns null.
2. The server action (processFile) now handles errors for individual brand names, ensuring that the entire process doesn't fail if one logo can't be fetched.
3. The LogoGrid component has been updated to display a placeholder when a logo couldn't be fetched.

These changes make the system more robust and able to handle cases where logos can't be found for certain brand names. The error you encountered should no longer occur, and the application will gracefully handle cases where logos can't be fetched.
