Microsoft Teams Node in n8n Fails to List Teams and Channels

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I am using the Microsoft Teams node in n8n and have configured my credentials with the URL https://teams.live.com/v2/?utm_source=OfficeWeb.

When I try to configure the parameters on the node, no list of Teams or Channels is displayed. Instead, the Chrome Developer Tools console shows a POST error:

POST <https://n8n2025.app.n8n.cloud/rest/dynamic-node-parameters/resource-locator-results> 500 (Internal Server Error)

The error message appears as: "Could not load list Please check your credentials." However, I have verified that the credentials are correct.

Below is my workflow for reference:

JSON

  “nodes”: [
    {
      “parameters”: {
        “operation”: “get”,
        “teamId”: {

          “mode”: “list”,
          “value”: “”
        },
        “channelId”: {
          “__rl”: true,
          “mode”: “list”,
          “value”: “”
        }
      },

        }
      }
    },

      “typeVersion”: 1,

      “id”: “0deb1814-7b66-43ef-ac6a-311c0a05a440”,
      “name”: “When clicking ‘Test workflow’”
    }
  ],
  “connections”: {
    “Microsoft Teams”: {
      “main”: [
        
      ]
    },
    “When clicking ‘Test workflow’”: {
      “main”: [
        [
          {
            “node”: “Microsoft Teams”,
            “type”: “main”,
            “index”: 0
          }
        ]
      ]
    }
  },
  “pinData”: {}
}

I expected to see a list of Teams and Channels, but I keep receiving the error message. What might be causing this issue, and how can I resolve it?

Based on the error message and the symptoms you described, one common cause is that the credentials are not pointing to the correct API endpoint. The Microsoft Teams node in n8n expects your credentials to be set up for the Microsoft Graph API, not for a URL like:

https://teams.live.com/v2/?utm_source=OfficeWeb

Here’s what you can do:

1. Update the API Endpoint in Your Credentials

Make sure you are using the correct endpoint for Microsoft Teams integrations via Microsoft Graph API. Typically, you should use something like:

https://graph.microsoft.com

Review the Microsoft credentials documentation to ensure that you have set up authentication correctly. Changing the configured URL in your credentials to the correct Microsoft Graph API endpoint is often the fix for the list not populating.

2. Re-Authenticate Recheck Permissions

After updating the endpoint:

Re-authenticate your credentials in n8n.
Confirm that the required scopes/permissions for managing Teams, channels, and messages are granted. Often, the Microsoft Graph scopes are required to fetch team and channel lists.

3. Verify Node Configuration

Once the credentials are corrected, try opening the dynamic parameters for the node again. If the configuration and authentication are successful, the list of Teams and Channels should load without the 500 error.

By ensuring you have the correct endpoint and the proper authentication setup via the Microsoft Graph API, you should resolve the “Could not load list Please check your credentials” error.
