What am I doing wrong in Clean Architecture?

public record TextRequest(List<string> List);
public record TextResponse(List<string> List);

public interface ITextService
    {
         Task<List<string>> ReadTextAsync(List<string> sourcePath);
         Task<string> HelloWorld();
    }

public class TextService : ITextService
{
    private readonly HttpClient _httpClient;
    public TextService(HttpClient httpClient)
    {
            _httpClient = httpClient; 
    }

        public async Task<List<string>> ReadTextAsync(List<string> sourcePath)
        {
            return await ProcessRepositoriesAsync(_httpClient, sourcePath);
        }

        private static async Task<List<string>> ProcessRepositoriesAsync(HttpClient client, List<string> sourcePath)
        {   
            var listOfTexts = new List<string>();
            foreach (var link in sourcePath)
            {
                var source = await client.GetStringAsync(link);
                listOfTexts.Add(source);
            }
            return listOfTexts;
        }

[ApiController]
[Route("text")]
public class TextController : ControllerBase
{
    private readonly ITextService _textService;

    public TextController(ITextService textService)
    {
  _textService = textService;
    }
    
   [HttpGet("gettext")]
   public IActionResult GetText(TextRequest request)
    {
var textResult =
_textService.ReadTextAsync(request.List);
var response = new TextResponse(textResult.Result);
return Ok(response);
    }
