I'm getting an error when attempting to create an Indexer for Sharepoint Online Indexer

Question

I'm getting the following error when attempting to create an Indexer for Sharepoint Online Indexer:

"Error with data source: A configuration issue is preventing authentication - check the error message from the server for details. You can modify the configuration in the application registration portal. See https://aka.ms/msal-net-invalid-client for details. Original exception: AADSTS7000215: Invalid client secret provided. Ensure the secret being sent in the request is the client secret value, not the client secret ID, for a secret added to app '3a2ab40b-f942-4b1e-8bf3-e9c5f79bb24f'. Trace ID: c217420b-24c1-4d5c-9291-ce6a4aab0f00 Correlation ID: 5257faf2-3c85-4bc2-a6ea-0342b1338399 Timestamp: 2025-03-09 15:10:15Z Please adjust your data source definition in order to proceed."

I'm using the following API endpoint: /indexers?api-version=2024-07-01

I've registered an app (in Entra) with id 3a2ab40b-f942-4b1e-8bf3-e9c5f79bb24f, and given the app a secret. I've also created a key in the keyvault.

I've successfully created a datasource (Sharepoint), and an Index.

The payload I'm sending to the endpoint is as follows.

Headers:

Content-Type: application/json
api-key: <this is the primary admin key assigned to my search service>

Body:

{

"name": "sharepoint-indexer",

"dataSourceName": "sharepoint-datasource",

"targetIndexName": "sharepoint-index",

"encryptionKey": {

"keyVaultKeyName": "SharepointIndexerKey",

  "keyVaultKeyVersion": <version of my the key in my keyvault>,

  "keyVaultUri": "<URI to my Keyvault>",

  "accessCredentials": {

    "applicationId": "3a2ab40b-f942-4b1e-8bf3-e9c5f79bb24f",

    "applicationSecret": <the **value** of a secret associated with the above Entra app>

  }

}

}

All the data sent with the API request seems to be fine, but I'm still getting an error. Any ideas what the issue might be?

Answer 1

Ok, I fixed this.

Looks as though it was all my fault too :D

I originally created my datasource with an early (preview) API version, rather than 2024-07-01, which I was using in an attempt to create my indexer.

I recreated everything using ?api-version=2024-11-01-preview, and the error dissappeared.

Btw, I think it's currently only possible to specify "sharepoint" as a datasource type if you're using a preview version of the API
