Adding OneDrive integration fails in 2025.2b

[SeanPM5]

The problem

Tried numerous times to set up the OneDrive integration and it was successfully linking to Nabu Casa (see image below):

But after this, it would show a blank "Error" dialog with no text at all:

Was unsure what was causing it, then when troubleshooting I visited my OneDrive account and noticed it was frozen, I assume due to a lengthy period of inactivity (it's attached to an outlook email that I never use so was unaware of this). Started the unfreeze account process which takes up to 24 hours.

This might be more of an edge case I guess, but would be nice if there was an informative error message (or even repair issue) when the OneDrive account is frozen.

Below is what was in system logs:

Looking at OneDrive support, it's not just account inactivity that can cause it to be frozen, but also can happen when exceeding storage quota: https://support.microsoft.com/en-us/office/what-does-it-mean-when-your-onedrive-account-is-frozen-5e76147b-b7d5-4bcb-ba28-b91e3eb636b6

I believe the free tier has 5GB storage which you can definitely exceed with HA backups. So this might end up being a more common scenario and not just an edge case.

I can't find anything in the docs how a frozen OneDrive responds. Since you are a developer, could you try installing msal and onedrive-personal-sdk and run the following code

import asyncio
from msal import PublicClientApplication
from onedrive_personal_sdk import TokenProvider, OneDriveClient
from onedrive_personal_sdk.const import HttpMethod, GRAPH_BASE_URL


class DummyAuthProvider(TokenProvider):

    def __init__(self, token: str):
        super().__init__()
        self._access_token = token

    def async_get_access_token(self) -> str:
        return self._access_token


async def main():
    app = PublicClientApplication(
        "afe53287-d3dd-4136-afa3-47b282ed76cd",
        authority="https://login.microsoftonline.com/consumers",
    )
    result = app.acquire_token_interactive(
        scopes=[
            "Files.ReadWrite.AppFolder",
        ]
    )
    token = result["access_token"]
    auth_provider = DummyAuthProvider(token)
    client = OneDriveClient(auth_provider)
    result = await client._request_json(
        HttpMethod.GET, f"{GRAPH_BASE_URL}/me/drive/special/approot:"
    )
    print(result)

asyncio.run(main())
