UiPathTeam.SharePoint.Activities - SharePoint Application Scope: 401 Unauthorized

Help Studio

Hello @radu_bucur, hope you are doing well.

I was trying to automate using SharePoint Application Scope, and for 7 out of 8 SharePoint sites I was able to connect and operate properly.
But there is this one that is outputting an “401: Unauthorized” error message, and I can’t seem to understand why.
I compared with other sites and it seems all the permissions are granted exactly the same.
Is there a specific permission I would have to be granted to access this site?

I can’t share sensitive information due to company policies but please let me know if you need any more details.

Hi Tika.

The 401 Unauthorized error message in SharePoint typically indicates that you do not have the necessary permissions to access the site. To resolve the issue, you can try the following steps:

  1. Check User Permissions: Ensure that you have the necessary permissions to access the site. You can check your user permissions in the site settings under the Users and Permissions section.
  2. Check Site URL: Ensure that you are using the correct URL to access the site. Sometimes a typo or incorrect URL can lead to a 401 error.
  3. Check Authentication Method: Ensure that you are using the correct authentication method to access the site. SharePoint supports several authentication methods, such as Windows, Forms-based, and Claims-based authentication.
  4. Disable Loopback Check: If you are accessing the site from the same server that is running SharePoint, you may need to disable the loopback check. The loopback check is a security feature that prevents an application from connecting to the SharePoint site that is running on the same server.
  5. Check for Firewall Restrictions: Ensure that your firewall is not blocking access to the site.
  6. Check for Active Directory Issues: If you are using Windows authentication, ensure that there are no issues with your Active Directory.
  7. Check for Site Collection Administrator: Ensure that the user account you are using has the necessary permissions to access the site collection.

These are a few steps you can try to resolve the 401 Unauthorized error message. If the issue still persists, you may need to consult with your SharePoint administrator or your IT department for further assistance.

This is a ChatGPT generated response if I’ve saw one! :stuck_out_tongue:

@Tika_Matias - please check out the Marketplace documentation of the Component, it contains some samples that hopefully can help you ensure that you’ve used the correct URL.

Otherwise, there is bound to be some sort of difference between the SharePoints Sites that are causing the problem.

It’s likely that this is a problem caused by invalid credentials or something of the sort. If it would’ve been a problem caused by insufficient permissions, I reckon you would’ve received a 403 Forbbiden response.

It would be helpful to know what authentication method you’re using?

The documentation helped to identify that indeed I was using the wrong URL.

It threw me off because I was used to receiving “Cannot contact site at specified URL…” for wrong URL’s error message.

Thank you so much!
