Question details

The user needs to resolve a 'file not found' error that occurs when trying to access an Angular application deployed within SharePoint Site Assets.

How to Fix SharePoint File Not Found Errors in Angular Applications

Product: Microsoft SharePoint
Device & OS: not provided
Scenario: Deploying an Angular application build (dist folder) to a custom SharePoint Site Assets directory for hosting.
Observed behavior: Accessing the deployed application URL, such as /SiteAssets/ServiceCapability/index.aspx, returns a file-not-found error instead of loading the Angular application.

Before you start

Ensure you have Site Owner or administrative permissions in SharePoint to manage Site Assets, view hidden files, and check document versions.

Solution 1Recommended

Verify File Path and Site Pages Configuration

Ensure the deployed Angular files exactly match the expected URL path and that the files have been properly checked in.

SharePoint requires precise path mapping for custom deployments. If the base URL in your Angular application does not match the SharePoint directory, or if the files are not checked in, the server will return a file not found error.

Navigate to Site Assets

Open your SharePoint Site Contents and click on the Site Assets or Site Pages library where the Angular dist folder was uploaded.

Check the exact file path

Verify that the file name and directory structure match your application URL exactly (e.g., /SiteAssets/ServiceCapability/index.aspx).

Check in the files

Select the uploaded files, click the ellipsis (...) menu, and choose 'Check in' or 'Publish' so that standard users can access them.

Verify File Path and Site Pages Configuration

Angular Base Href: When building your Angular app, ensure you use the --base-href flag pointing directly to your SharePoint folder path to prevent asset routing errors.

Solution 2

Review Document Version History

If the file was overwritten by a flawed deployment or accidentally deleted, restoring a previous working version can resolve the error.

Solution 3

Seek Help in the SharePoint Developer Community

Since deploying Angular applications involves custom SharePoint development, Microsoft community experts can provide specialized architectural guidance.

Frequently Asked Questions

Why does my SharePoint site return a 404 error for uploaded assets?

A 404 file-not-found error usually occurs if the file hasn't been checked in, is published as a draft that standard users cannot see, or if the URL path contains a typo.

Can I host an Angular application directly in SharePoint Site Assets?

Yes, you can upload the built dist folder to Site Assets. However, you must ensure the base href in your Angular configuration matches the SharePoint site path exactly, otherwise, the application will fail to load its internal assets.

How do I access hidden files in a SharePoint library?

You can view hidden files by modifying the library view settings to show all items without folders, or by accessing the site via SharePoint Designer, provided you have the necessary site administrator permissions.
