File Handler custom action fails to open new browser tab in OneDrive personal app for Teams desktop client

[kpoimenidis]

Description:
In the OneDrive personal app for the Teams desktop client, clicking the file handler custom action does not open a new browser tab as expected. Although the network activity in the developer tools shows that a request is sent to obtain a pre-authorized URL for the file, no subsequent action occurs to open a browser tab with the file.

Steps to Reproduce:

1. Open the OneDrive personal app within the Teams desktop client.
2. Select any file in your OneDrive repository.
3. Click on the file handler custom action.
4. Observe in the browser’s developer tools (Network tab) that a request is sent to retrieve a pre-authorized URL.
5. Note that despite the successful network request, no new browser tab open.

Expected Behavior:
Clicking the file handler custom action should result in opening a new browser tab that navigates to the URL for this action.

Observed Behavior:
The request for the pre-authorized URL is initiated and appears successful in the network logs.
No new browser tab opens, preventing access to the file via the expected workflow.

Environment:
Client: OneDrive personal app within Teams desktop client
Operating System: macOS
Teams Version: 25060.203.3471.5023
File Types: any

Hey @kpoimenidis , thanks for bringing this to attention. I've made a fix to launch us into a proxy window, it should hopefully be fixed by 4/21 or 4/28 depending on if my fix gets in this week's build or not.

In the meantime, can you check if this same issue occurs when attempting to perform the action from the Recent, Shared, or Favorites pivot? I believe it should work there

Hi @JCrew0, thank you for your quick action on this.

I don't see the custom actions being available at all in the pivots you mentioned. For the Recents pivot, I am certain that they never were. Our file handler app adds two custom actions, so I am not sure if other types of actions are available in those pivots.
