I found a similar unsolved discussion regarding issues with uploading images in Dify's workflow via API. You can check it out here [1].

Regarding your issue, the error "img1 value can not be empty" might be related to the specific validation rules for file uploads in the 'Explore' section of Dify. Here are some key points to check:

  1. File Presence: Ensure that the file is included in the request. If not, a NoFileUploadedError might be raised.
  2. Filename Requirement: The file must have a filename. If not, a FilenameNotExistsError might be raised.
  3. Supported File Type: Ensure the file type is supported to avoid an UnsupportedFileTypeError [2].

Since the issue does not occur in the "Studio" section, it might be worth checking if there are any specific configurations or settings that differ between the "Explore" and "Studio" sections, although I couldn't find specific information on this [2].

To continue talking to Dosu, mention @dosu.
