Drives SDK - Get Items Children Not working

[kosik]

Describe the bug

Here is the link to official documentation: driveitem-list-children

Here is the code snippet from there:

// Code snippets are only available for the latest version. Current version is 6.x GraphServiceClient graphClient = new GraphServiceClient(requestAdapter); DriveItemCollectionResponse result = graphClient.drives().byDriveId("{drive-id}").items().byDriveItemId("{driveItem-id}").children().get();

The documentation states if pass "root" into byDriveItemId method, the SDK will return the list items of the root directory. In fact this method returns empty collection.

I verified if the API works with plain HTTP invocation through MS Graph Explorer, and there are many items in response. So I have took one of the identifiers from the response manually and put it into byDriveItemId. The API returned com.microsoft.graph.models.odataerrors.ODataError: The resource could not be found. I anticipated to see the list of files inside the directory of the root drive.

As you see the sample from official Java SDK documentation does not working. I start guessing and attempted other variants to let the SDK works but did not succeed.

Could you please provide a working code snippet allowing to receive a list of files of a given URL in a shared directory or fix the BUG.

Belowe I am attaching my code, configurations and more details:

https://login.microsoftonline.com/_my-ID-here_/oauth2/v2.0/authorize?client_id=XXX&response_type=code&redirect_uri=https://my-domain.com/az-token&response_mode=query&scope=https://graph.microsoft.com/Files.Read.All User.Read offline_access Sites.Read.All&

` private String[] scopes = new String[]{"Files.Read.All", "User.Read", "offline_access", "Sites.Read.All"};

public void getData(final String code){
    List<DriveItem> rootItems = getGraphClient(code).drives()
            .byDriveId(myDriveId).items().byDriveItemId("root").children().get().getValue();
    rootItems.size();
}

private GraphServiceClient getGraphClient(final String authorizationCode) {
    if(null == authorizationCode)
        throw new DomainException(ErrorCodes.InvalidInput, "msgraph-pkce-code-required");

    GraphServiceClient graphClient = null;
    if (null == graphClient) {
        final AuthorizationCodeCredential credential = new AuthorizationCodeCredentialBuilder()
                .clientId(CLIENT_APP_ID).tenantId(TENANT_ID).clientSecret(CLIENT_APP_SECRET)
                .authorizationCode(authorizationCode).redirectUrl(AUTH_REDIRECT_URL).build();

        if (null == scopes || null == credential) {
            throw new DomainException(ErrorCodes.InvalidInput, "msgraph-initialization-error-00");
        }

        graphClient = new GraphServiceClient(credential, scopes);
    }
    return graphClient;
}`

Thank you in advance.

Expected behavior

to see the list of files inside the directory of the root drive.

How to reproduce

I have configured the required permissions in Azure portal for my application: Files.Read.All User.Read offline_access Sites.Read.All

After this a put the below URL into browser location string. Which lead to login and passing the token into my application controller. The getData(final String code){ received the code and passed authorization successfully. Nevertheless, the subsequent Children Items list API execution does not working even with the example from official documentation code snippet.

https://login.microsoftonline.com/_my-ID-here_/oauth2/v2.0/authorize?client_id=XXX&response_type=code&redirect_uri=https://my-domain.com/az-token&response_mode=query&scope=https://graph.microsoft.com/Files.Read.All User.Read offline_access Sites.Read.All&

Hi @kosik, unfortunately I'm unable to reproduce this behavior. Are you able to double-check that you're using the right drive ID?

[kosik]

@Ndiritu thank you for the answer. The driveId is correct for sure, the value in myDriveId variable is my drive identifier.

@kosik please clarify what request you tested on Graph Explorer: /drives/{drive-id}/items/root/children? From your description it seems that this is the URL you called & that you used an ID from one of the results as your new "drive ID"?
