API error while trying to upload File

Using the Java SDK I'm trying to upload a test file but getting the below API exception

Exception in thread "main" com.box.sdk.BoxAPIException: The API returned an error code: 400

I'm able to successfully authenticate the user and also create a folder but unable to upload a file. Below is my Java code

public static void main(String[] args) throws Exception {

        String path = new File("").getAbsolutePath();
        Reader reader = new FileReader(path.concat("/").concat("src/main/resources/config.json"));
        BoxConfig boxConfig = BoxConfig.readFrom(reader);

        JWTEncryptionPreferences encryptionPref = new JWTEncryptionPreferences();
        encryptionPref.setPublicKeyID(boxConfig.getJWTEncryptionPreferences().getPublicKeyID());
        encryptionPref.setPrivateKey(boxConfig.getJWTEncryptionPreferences().getPrivateKey());
        encryptionPref.setPrivateKeyPassword(boxConfig.getJWTEncryptionPreferences().getPrivateKeyPassword());
        encryptionPref.setEncryptionAlgorithm(EncryptionAlgorithm.RSA_SHA_256);

        IAccessTokenCache accessTokenCache = new InMemoryLRUAccessTokenCache(MAX_CACHE_ENTRIES);

        BoxDeveloperEditionAPIConnection api = BoxDeveloperEditionAPIConnection.getAppEnterpriseConnection(
                boxConfig.getEnterpriseId(), boxConfig.getClientId(), boxConfig.getClientSecret(), encryptionPref, accessTokenCache);

        BoxUser.Info userInfo = BoxUser.getCurrentUser(api).getInfo();
        System.out.format("Welcome, %s!\n\n", userInfo.getName());

        BoxFolder rootFolder = BoxFolder.getRootFolder(api);
        Iterable infoIterable = rootFolder.getChildren();
        Iterator iterator = infoIterable.iterator();
        while (iterator.hasNext()) {
            BoxItem.Info info = iterator.next();
            if (info instanceof BoxFolder.Info) {
                BoxFolder.Info folderInfo = (BoxFolder.Info) info;
                uploadFile(path.concat("/").concat(FILE), api, folderInfo.getResource());
            }
            System.out.println("Item name is " + info.getName());
        }

        System.out.println("folder owner: " + rootFolder.getInfo().getOwnedBy().getName());
    }

   private static String uploadFile(String pathFileName, BoxAPIConnection api, BoxFolder folder) {
        boolean fileExists = false;
        String fileId = null;

        try {
            String fileName = pathFileName.substring(pathFileName.lastIndexOf("/")+1, pathFileName.length());

            for (BoxItem.Info itemInfo : folder) {
                if (itemInfo instanceof BoxFile.Info) {
                    BoxFile.Info fileInfo = (BoxFile.Info) itemInfo;
                    if (fileName.equals(fileInfo.getName())) {
                        fileExists = true;
                        fileId = fileInfo.getID();
                    }
                }
            }

            if (!fileExists) {
                System.out.println("uploading new file: " + fileName);
                FileInputStream stream = new FileInputStream(pathFileName);
                BoxFile.Info boxInfo = folder.uploadFile(stream, pathFileName);
                fileId = boxInfo.getID();
                stream.close();
            }
            else {
                System.out.println("uploading new version of file: " + fileName);
                BoxFile file = new BoxFile(api, fileId);
                FileInputStream stream = new FileInputStream(pathFileName);
                file.uploadVersion(stream);
                stream.close();
            }
        }
        catch (IOException e) {
            System.out.println(e);
        }
        return fileId;
    }
}

Hi akubatoor,

Would you happen to have the error message that's sent with the 400 status code in the Box API response? That'll help narrow down the reason for the 400.

Thanks,

Jon

The response is 400 item_name_invalid

From https://community.box.com/t5/Managing-Content-Troubleshooting/File-and-Folder-Upload-Issues/ta-p/306

Verify that the file's name is valid. Box only supports file or folder names that are 255 characters or less. File names containing non-printable ascii, "/" or "\", names with leading or trailing spaces, and the special names “.” and “..” are also unsupported.

I don't think I'm giving any invalid file name. I'm trying to upload a file with the name taxdoc.txt. Below the API response I'm seeing

{"type":"error","status":400,"code":"bad_request","context_info":{"errors":[{"reason":"invalid_parameter","name":"entity-body","message":"Invalid value '{\"name\":\"taxdoc.txt\", \"parent\":{\"id\":\"0\"}'. Entity body should be a correctly nested resource attribute name\/value pair"}]},"help_url":"http:\/\/developers.box.com\/docs\/#errors","message":"Bad Request","request_id":"***number removed for privacy***597673fe85807"}

I just ran your code and made one change and it seems to work fine.

I changed pathfileName to fileName in the method call folder.uploadFile()

if (!fileExists) {
    System.out.println("uploading new file: " + fileName);
    FileInputStream stream = new FileInputStream(pathFileName);
    BoxFile.Info boxInfo = folder.uploadFile(stream, fileName);  // <- this is just the name and not the full path
    fileId = boxInfo.getID();
    stream.close();
}

Yeah right..I also had changed the code a little bit to get this working. I changed it something like below

if (!fileExists) {
                FileInputStream stream = new FileInputStream(pathFileName);
                FileUploadParams fileUploadParams = new FileUploadParams();
                fileUploadParams.setName();
                fileUploadParams.setContent(stream);
                BoxFile.Info boxInfo = folder.uploadFile(fileUploadParams);
                fileId = boxInfo.getID();
                stream.close();
            }

Hey,
