This is the result I get when I try to send a 350kb file 3 times in Base64 format in one request to the Parse Cloud Code function. What does it mean? Can I send it somehow? This is important to me because I use Parse as my server and I want my device to be independent of file storage due to Parse limitations (I want to use external storage like amazon in the future).
