I guess the API is unable to locate or retrieve the image specified in your analysis request. This could be due to various reasons
Ensure that the URL provided for the image in your analysis request is correct and accessible please Verify that the URL is publicly accessible from the internet.
Confirm that the image is hosted on a server that allows external access. If the image is hosted locally then it may not be reached
and finally check If your image URL contains special characters, make sure it is properly URL-encoded. Special characters in URLs can cause issues if not encoded correctly.
If this helps kindly accept the answer thanks much.
