addFile(fileName, file) not work

[fr4style]

Hi, today I try to use the addFile function to attach a photo into an email. My code is like the README:

for(j = 0; j < images.length; j++){
    console.log(images[j]);
    email.addFile("Allegato_"+(j+1)+".jpg", images[j]);
}
sendgrid.sendEmail(email);

The images[j] is a ParseFile, and the log print the value correctly, but the email sent is without attachments. Please can you check the method or help me? Thank you, -Francesco

The addFile method returns a Promise. You need to wait for it to be completely executed.

email.addFile('filename', file).then(function(e) {
    console.log(e);
});

Hi elbuo8, thank you for the precious support. I changed my code using a recursive method that attaches all files of the array and sends the email when the array ends:

function attachToEmailAndSend(email, index, attachments){
        email.addFile("Allegato_"+(index+1), attachments[index])
        .then(function(e) {
                            index++;
                console.log(" -- index: "+index+", size: "+attachments.length);
                if(index < attachments.length){
                    attachToEmailAndSend(email, index, attachments);
                }else{
                    sendgrid.sendEmail(email)
                        .then(function(httpResponse) {
                          console.log(httpResponse);
                        },function(httpResponse) {
                          console.error(httpResponse);
                    });
                    console.log(" -- Email Sent");
                }
        });
}

Unfortunately I incurred in this error:

  Result: URIError: URI malformed
    at encodeURIComponent (native)
    at <anonymous>:325:38
    at Parse.js:1:20710
    at Array.forEach (native)

    at SendGrid.send (sendgrid.js:292:19)
    at SendGrid.sendEmail (sendgrid.js:325:17)

Please, can you help me again?

Thank you, -Francesco

Try using promise.all pattern to iterate through your array of files then perform the sending. https://www.promisejs.org/patterns/ (Not sure if supported by Parse.promise)

Thanks you, but unfortunately If i remove recursive method, I have the same error. The code now is:

function attachToEmailAndSend(email, index, attachments){
        email.addFile("Allegato_"+(index+1), attachments[index])
        .then(function(e) {
                    sendgrid.sendEmail(email)
                        .then(function(httpResponse) {
                          console.log(httpResponse);
                        },function(httpResponse) {
                          console.error(httpResponse);
                    });
        });
}

and the error is the same of the last post.

Why the file object should be wrong or malformed? It's so strange...

However, thank you for the support, -Francesco

Native encodeURIComponent may throw Error if you try to encode binary file ut8 representation. It should work fine for text files though.
