I thought you are accessing document preview of OneDrive files but you can access different drives from here

Hi Vaibhav,

Actually we can get the Library drive id using the below graph api. If you run the below api url in the graph explorer.you will get all the libraries with it's drive id.

https://graph.microsoft.com/v1.0/sites/{siteid}/drives

https://graph.microsoft.com/v1.0/me/drive/ this is representing our personal one drive id i guess.

Your drive id will be the same
you can also access it using the below graph API
https://graph.microsoft.com/v1.0/me/drive/

There will be an id field in the response that is drive id.

Hi Vaibhav,

I tried this but the drive id which is showing in this graph explorer and drive id which is showing while inspecting the thumbnail image of the tiles view of the document library both are different.

I don't know about the cb parameter but I don't think it is a required property when accessing the thumbnail of any file according.

You can check here:
https://docs.microsoft.com/en-us/onedrive/developer/rest-api/api/driveitem_list_thumbnails?view=odsp-graph-online

Also, you can find the drive id in Microsoft Graph explorer. You can fetch your all document in OneDrive there you will find your drive id.
