Hello David_Chan2255,
Implement error handling to capture and log the exact error message returned by the API. This can provide more insights into why the request is failing.Here is a sample code snippet to fetch the image using the Graph API token:
using System.Net.Http; using System.Net.Http.Headers; using System.Threading.Tasks; public async Task<byte[]> DownloadImageAsync(string imageUrl, string accessToken) { using (var httpClient = new HttpClient()) { httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", accessToken); var response = await httpClient.GetAsync(imageUrl); if (response.IsSuccessStatusCode) { return await response.Content.ReadAsByteArrayAsync(); } else { throw new HttpRequestException($"Failed to download image. Status code: {response.StatusCode}"); } } }Make sure to replace imageUrl with the actual URL of the image and accessToken with the valid Graph API token.
