Microsoft.Graph HTTP REST call problem

Question

I’m trying to make an HTTP Get call to Microsoft.Graph to retrieve data from files and folders stored in an application’s Root folder.

The following calls work correctly:

https://graph.microsoft.com/v1.0/me/drive/special/approot:/my_file.txt

https://graph.microsoft.com/v1.0/me/drive/special/approot:/Folder/image.png

Both of these calls return full JSON files.
For example, the second call returns:

{
“@odata.context”: “https://graph.microsoft.com/v1.0/$metadata#users(‘user%40outlook.com’)/drive/special/$entity”,
“@microsoft.graph.downloadUrl”: “https://public.am.files.1drv.com/y4mhyIFsH6p4JLCJ9ytqAXo_3wNXX_jR5wV2c5GZFo05b8vCDUGE-fMRxoNqksiR4ZvLa1P71bTQ6iG6Q5iPqpXU7go1UX3-pydXv94EMorZ qEqjYcQabXDcVMt3FhH8QxRxbFCurpSiLAlFkYPzbp31mKxsLItuSm0OeiySvAGusGj5LpHZd7jmcq61S1IMfg5z2wXGmBpqV5jqpM22WdE11TzthG11y7E-e3OsD-hlhU5AtJ8kcn9 yXX1AbW2kTgv”,

},

},

},

}
},
“fileSystemInfo”: {
“createdDateTime”: “2023-11-08T09:18:56.38Z”,

},
“picture”: {
“height”: 600,
“width”: 600
},
“photo”: {}
}

But the following call does not work:

https://graph.microsoft.com/v1.0/me/drive/special/approot:/Folder

It does not output an error, but only returns the JSON:

{
“@odata.context”: “https://graph.microsoft.com/v1.0/$metadata#users(‘user%40outlook.com’)/drive/special(‘approot%3A’)/folder”
}

Why is the data returned not complete?

But, if on OneDrive there is a folder named “MyFolder”, reading it via the URL
https://graph.microsoft.com/v1.0/me/drive/special/approot:/MyFolderworks perfectly.

So I think “Folder” is a reserved word with a special meaning.

Question: how do I access a folder called “Folder” or “folder”?

Another question is there, in the same context, other reserved keywords?

Best regards

Answer 1

Hi,

I am unable to find any reference which mentions that the Folder is a reserved keyword.

You can try accessing the Folder as mentioned below:

GET v1.0 https://graph.microsoft.com/v1.0/me/drive/special/approot/children?$filter=name eq 'Folder'
