Error reading from INBOX via IGraphAPI

I am encountering an error in the GraphAPI while fetching emails from inbox

The following code

        GraphFolderInfo info = client.getFolder(GraphKnownFolders.Inbox);
        System.out.println(info.getItemId());
        GraphMessageInfoCollection messageInfoColl2 = client.listMessages(info.getItemId());
        for (GraphMessageInfo messageInfo : messageInfoColl2) {
            System.out.println(messageInfo.getSubject());
        }

causes an

Exception in thread "main" AsposeBadServerResponceException: Server error [400] Operation failed.: 400/Bad Request
Details:   
{
  "error": {
    "code": "BadRequest",
    "message": "Resource not found for the segment 'AAAA.....='.",
    "innerError": {
      "date": "2021-04-14T10:38:43",
      "request-id": "380......",
      "client-request-id": "380....."
    }
  }
}

From our proxy, i see that it tries to call
/v1.0/users/xxx@zzzz.tld/mailFolders/inbox/AAMxxxxx…=/messages?..
So it looks like the api considers the inbox folder to be a subfolder of inbox when using the actual itemId of the inbox folder…

@fxhak,
Thank you for the issue description. I have logged the issue in our tracking system with ID EMAILJAVA-34859. Our development team will investigate it. I will inform you about any progress.

@fxhak,
Our development team is working on a solution to the issue. But now you can use GraphKnownFolders.Inbox enumeration value instead of client.getFolder method as below:

GraphMessageInfoCollection messageInfoColl = client.listMessages(GraphKnownFolders.Inbox);
for (GraphMessageInfo messageInfo : messageInfoColl) {
    System.out.println(messageInfo.getSubject());
}

Documentation: List Messages
API Reference: IGraphClient interface

Thanks! For the info. Unfortunately, using this workaround is really complex as my app has seperate functions for listing folders and getting the messages of a folder…

Along the same lines

GraphFolderInfo info = client.getFolder(GraphKnownFolders.Inbox);
client.listFolders(info.getItemId())

causes the same error whereas

client.listFolders(GraphKnownFolders.Inbox);

Results in a

com.aspose.email.internal.hw.zb: JSONObject["value"] not found.

The url called seems to be
/v1.0/users/x@y.z/mailFolders/inbox
so it looks to me like it misses the childFolders path

@fxhak,
Thank you for the additional information. We will take it into account for investigation.

@fxhak,
The issues you described have been fixed in a separate build: Aspose.Email 21.3.1. Please try to use it.

The issues you have found earlier (filed as EMAILJAVA-34859) have been fixed in this update.
