OneDrive Embeded View - error with "odsp.react.lib"

Question

OneDrive Embeded View - error with "odsp.react.lib"

Sławomir Poprawa 5

Hi!

For a few days now we are unable to view any document in Embeded View.

The EmbedView's RequireJS configuration references odsp.react.lib-f74dfea2, but the CDN returns 404 error of:

https://res-1.cdn.office.net/files/sp-client/odsp.react.lib-f74dfea2.js

Therefore, there is no way to view embeded document in Embeded View (otherwise document works fine).

Is there any way to fix this?

I can confirm that I am experiencing the same odsp.react.lib / 404 issue with OneDrive EmbedView.

Since August 21, 2026, embedded Excel workbooks display a blank white screen. The browser console reports: Uncaught Error: Script error for "odsp.react.lib". The requested odsp.react.lib-f74dfea2.js file on res-1.cdn.office.net returns HTTP 404 with BlobNotFound.

I reproduced the issue with both my existing workbook and a newly created empty workbook. The same workbooks open normally in Excel for the web. I also generated a new EmbedView URL for the workbook, with the same result.

The issue reproduces in Firefox as well as Chromium-based browsers (Chrome, Edge and Opera), so it does not appear to be specific to a particular browser engine.

I contacted Microsoft Support about this and was advised that the issue appears to be related to the Microsoft-hosted OneDrive EmbedView service and would require investigation by the engineering team.

Hopefully this helps confirm that the issue is not limited to a specific workbook or browser.

That's correct - everything You wrote is accurate.

I'm doing some tests for support right now, because they cannot simply check if this library actually exists :) ... that's to complicated. They cannot push this to engineering team without tons of logs, screenshots and screen recordings...

Anyway - still fighting. Will update this if something changes.

P.S. Thanku You @Xavier-D ! Your response has set me on right track with this hole issue!

Hello Sławomir Poprawa

I can see that you are having issue with OneDrive Embeded View

The console evidence indicates that the OneDrive EmbedView is trying to load a required Microsoft-hosted JavaScript dependency, but the CDN returns a 404 error. Because that dependency does not load, the viewer cannot initialize and only displays a blank screen.

For now, the practical workaround is to open the document directly in OneDrive or Excel for the web or download it where appropriate.

I recommend contacting Microsoft Support and providing the failed resource name, build information, EmbedView mode so the issue can be escalated to the responsible service team:

Please note that this is a user-to-user support forum. Moderators and contributors, including external Microsoft employees, are not allowed to directly interfere with Microsoft product features or access back-end systems. Our role is limited solely to providing technical guidance on reported incidents, requests, or ideas.

Open a website link - Contact - Microsoft Support
In the box below "We're here to help", type Microsoft 365, click "Get Help", and then click "Contact Support" below.
In this section, you will need to sign in to your Microsoft account.
Select "Microsoft 365 and Office" under Products & Services, select "Technical Support" as the category, and click to confirm
You can select " Chat with a support agent in your web browser " to access the chat window.

I understand this is disruptive, especially when the embedded viewer is part of an existing workflow, and I hope the service team can address the missing dependency promptly.

I hope you can get the support you need, have a nice day.
