Unable to get file drive item via /shares/{encoded_webUrl} after listing children

Question

I encountered an issue when getting a drive item via /shares endpoint. After listing drive items via /me/drive/root/children and using encoded webUrl in /shares endpoint (as described here ) graph api returns "invalidRequest: Invalid shares key." error. After some investigation I found that webUrl of drive items changed about 2-3 weeks ago. Before, listing drive items (like .xlsx files) would return webUrl similar to: https://onedrive.live.com/personal/946c98d07c563ce7/_layouts/15/doc.aspx?resid=946C98D07C563CE7!381&cid=946c98d07c563ce7

Now, however, webUrl looks similar to: https://onedrive.live.com/personal/946c98d07c563ce7/_layouts/15/doc.aspx?resid=7c563ce7-98d0-206c-8094-7d0100000000&cid=946c98d07c563ce7

So only resid is different, and after encoding current webUrl and using it in /shares endpoint graph api returns an error. I tested this with Postman. To access graph api I am using OAuth2.0 access token with "Files.ReadWrite offline_access" scopes. I am unable to find any change logs regarding this change, so is there some changes I need to make to my Entra application that I am using in OAuth2.0 flow to return webUrl as it was before? If not, how can I use the new webUrl in the /shares endpoint without manually editing it? It is vital for me to use /shares endpoint.
Thank you.

Hi @Oleksandr

For this problem, you can try the following two approaches.

According to the documentation, you need to first create a shared link for the DriveItem that you want to share, and then encode that link.

When you create a shared link, shareId is also returned, and according to the documentation, you can also use shareId for access.

Hope this helps.
