Before trying with an image from a web address, I already tried with an image obtained from a camera and then from the image upload control, however I still get the same message.
"Invalid argument type (Image). Expecting a UntypedObject value instead.", the image is supposed to be in the correct format already.

The ComputerVisionAPI.OCRTextV2 function expects an image in a special format, but you're giving it text (a URL), which it doesn't understand.

Can you try giving it the actual image (not just a link)? If you're using a camera or an uploaded file, pass the image object instead of a text URL.

For example if you're using a camera

Set(
OCRResult,
ComputerVisionAPI.OCRTextV2(
{
Image: CameraControl.Photo, // Use the image captured by the camera
Language: "en", // Language for text
DetectOrientation: true // Automatically detect text orientation
}
)
);

If you have a file or image try to use a method to upload or directly reference the binary data of the image (check how you’re storing or uploading the image).
