Hi, 

I am new to the box api. I have gone through the java box sdk and trying out to get connection with box with java client. I am simply printing the root folder in the below code but it is throwing an error:

package com.box.api.test;
import java.io.FileReader;
import java.io.IOException;
import java.io.Reader;

import com.box.sdk.BoxAPIConnection;
import com.box.sdk.BoxConfig;
import com.box.sdk.BoxFolder;

public class BoxAPIConnectionTest {
public static void main(String[] args) throws IOException {
Reader reader = new FileReader("resources/config.json");
BoxConfig boxConfig = BoxConfig.readFrom(reader);
BoxAPIConnection api = new BoxAPIConnection(boxConfig);
BoxFolder root_Fol=BoxFolder.getRootFolder(api);
System.out.println(root_Fol.getInfo().getID());
}
}

Error:
Exception in thread "main" com.box.sdk.BoxAPIResponseException: The API returned an error code [401 | .08e718937be17e68094d8f7a2c2ee84c]

at com.box.sdk.BoxFolder.getInfo(BoxFolder.java:288)
at com.box.api.test.BoxAPIConnectionTest.main(BoxAPIConnectionTest.java:16)

    Hi ,

     

    This may be due to a few things - let's check off a few of the most common:

    1. Within the scopes of your application can you try setting "read and write all folders" to on if not already set.
    2. Did you (or your enterprise admin) authorize the app to work in the enterprise? You'll also need to reauthorize whenever there are scope changes to the app. If a JWT app isn't authorized it'll prevent you from making API calls. 

    Hopefully one of those is the cause,

    Jon

    App Scopes: as below
    BOX_roglr1tyxbqrp1qkf4gu0n3g913hq5bp.pngapplication scopes

     

    and also authorized this app twice but still couldn't. and my self is the admin and there were no other users created.
