Skip to main content

BoxFile file = new BoxFile(boxAPIConnection, "Some-id");
try (FileOutputStream stream = new FileOutputStream(fi)) {
    file.download(stream);
    // Do Sth
}

At the line file.download(stream) I got an error


java.lang.NullPointerException: Cannot invoke "java.io.InputStream.read(byte[])" because "input" is null
    at com.box.sdk.BinaryBodyUtils.writeStreamTo(BinaryBodyUtils.java:55)
    at com.box.sdk.BinaryBodyUtils.writeStream(BinaryBodyUtils.java:41)
    at com.box.sdk.BoxFile.download(BoxFile.java:311)
  at com.box.sdk.BoxFile.download(BoxFile.java:298)

 

I look at the lib of box sdk and see that this line got nullpointer exception beacause the input is null. This only happens when I try to upload an empty txt file then download it.
