Fix 404 Error When Loading Documents in React Document Editor

30 Jul 20261 minute to read

If document loading fails and you see a 404 error in the browser console, the React Document Editor (Document Editor) is unable to reach a valid Web Service endpoint.

Reasons

The 404 error may occur due to the following reasons:

  • The Web Service is not running or inactive – When hosting your own Web Service, the server may be stopped, not deployed correctly, or configured such that required endpoints (e.g., /Import, /SpellCheck) return 404.
  • The configured serviceUrl is invalid – A missing trailing slash (/), wrong port, incorrect API route, or typos cause the editor to call invalid endpoints.
  • The application is using an old or discontinued Document Editor service URL – When using an old Document Editor service URL that is no longer valid.

Solutions

  • Update the application to use the new hosted Document Editor Web Service URL introduced in v31.x.x. For example:

      container.serviceUrl = 'https://document.syncfusion.com/web-services/docx-editor/api/documenteditor/';

NOTE

The hosted Web Service link is provided for demonstration and evaluation only. For production deployment, please host your own Web Service with your required server configurations. You can refer and reuse the GitHub Web Service example or Docker image for hosting your own Web Service and use it for the serviceUrl property.

  • If you are using your own hosted Web Service, ensure that the Web Service is running, active, and the configured service URL is valid.
