@dosubot[bot] commented on GitHub (Dec 16, 2024):

The error message "The requested resource isn't a valid image" could be related to several factors in the Dify platform. Here are some potential causes and solutions:

  1. Supported Image Formats: Ensure that the image you are trying to use is in one of the supported formats: JPG, JPEG, PNG, GIF, WEBP, or SVG [1].

  2. Image Size Limit: Check if the image exceeds the size limit of 10 MB. If it does, try reducing the image size [2].

  3. Image Validation Logic: The image validation logic is implemented in the File class within the api/core/file/models.py file. You might want to review this logic to ensure that the image meets all the validation criteria [3].

  4. Configuration Settings: Verify the configuration settings related to image handling, such as FILES_URL and MULTIMODAL_SEND_IMAGE_FORMAT, to ensure they are correctly set up for your environment [4].

By checking these aspects, you might be able to identify and resolve the issue with the custom icon error.

Can you try to upload the image again? I reproduced this. Will fix it later.
