Hi Alex,
sorry to bother you again .
I get this error while i'm tryng to create the object to send to an ftp server, here is my code:

Code: Select all

switch (acquireModalState) {
                case 2:   // image is acquired
                    // get acquired image
                    var acquiredImage = acquireModalResult.get_AcquiredImage();
                    // add acquired image to the collection of acquired images
                    acquiredImages.add(acquiredImage);
                    
                    console.log(acquiredImages);
                    break;
                case 4:   // scan is failed
                    alert(acquireModalResult.get_ErrorMessage());
                    break;
                case 9:   // scan is finished
                let params = {};
                var imageIds = []
                    // for each acquired image
                    for (var i = 0; i < acquiredImages.get_Count(); i++){
                        // add image identifier to array of image identifiers
                        imageIds.push(acquiredImages.get_Item(i).get_Id());
                    }
                    // save images to an image file and return file data as a Base64 string
                    var imageFileAsBase64String = acquiredImages.getAsBase64String(nome_file+'.pdf', imageIds);
                    params.fileToUpload = imageFileAsBase64String;

Find it!

There is a mistake in your Tutorial section : https://www.vintasoft.com/docs/vstwain ... rver.html .

The function is : *.getItem() , not *get_Item() .

Thank you anyway.
Best Regards,
Luigi
