rename folder causes BoxAPIException

[joh-mue]

The following code will raise a BoxAPIException everytime it is executed. The renaming goes through but the Exception is thrown.

[BoxAPIException: Couldn't finish closing the connection to the Box API due to a network error or because the stream was already closed.]

This is my code

public static void renameFolder(String developerToken, String folderID, String name) {
    BoxAPIConnection connection = new BoxAPIConnection(developerToken);
    BoxFolder folder = new BoxFolder(connection, folderID);
    folder.rename(name);
}    

Am I stupid or is there maybe something wrong here?

Hi @joh-mue, sorry for the delayed response. What you're doing looks correct.

Can you paste the full stack trace including the inner exception? Which version of the SDK are you using?

Well, now it took me a very long time. Here's what I get:

Thank you for your help!

Hi @joh-mue, are you still running into this issue? If so, please reopen this ticket.

So far I've been unable to reproduce it, but it definitely looks like some other code is closing the HttpUrlConnection before BoxAPIResponse.disconnect() is called. Is it possible that there's any other code in your program that could be doing this? It may also just be happening if the network connection is interrupted.

I am using the box java sdk 2.8.2 to move some folders around as a part of automation.

A call to public BoxFolder.Info moveFolderToUser​(String sourceUserID) throws the following exception . The move happens succesfully but the BoxFolder.Info object returned is null. Looks like a similar issue
