I am setting up an indexer for our sharepoint library to interact with Azure AI Search. Here is the Datasource (Yes I am sending requests from a C# solution)

var url = "https://[search service here].search.windows/datasources?api-version=2023-07-01-Preview";
var apiKey = "INSERT KEY HERE";
var connectionString = "SharePointOnlineEndpoint=https://[INSERT COMPANY HERE].sharepoint/sites/GCHighlines;ApplicationId=[APPLICATION ID HERE];";

var requestBody = new
{
    name = "sharepoint-datasource",
    type = "sharepoint",
    credentials = new { connectionString = connectionString },
    container = new { name = "useQuery", query = "includeLibrary=https://[INSERT COMPANY HERE].sharepoint/sites/GCHighlines/Shared%20Documents/Forms/AllItems.aspx?id=%2Fsites%2FGCHighlines%2FShared%20Documents%2FEditing%20Highlines%2FBROO" }
};

Below is the request to create the Indexer:

{
    "name" : "sharepoint-indexer",
    "dataSourceName" : "sharepoint-datasource",
    "targetIndexName" : "sharepoint-index",
    "parameters": {
    "batchSize": null,
    "maxFailedItems": null,
    "maxFailedItemsPerBatch": null,
    "base64EncodeKeys": null,
    "configuration": {
        "indexedFileNameExtensions" : ".pdf, .docx",
        "excludedFileNameExtensions" : ".png, .jpg",
        "dataToExtract": "contentAndMetadata"
      }
    },
    "schedule" : { },
    "fieldMappings" : [
        { 
          "sourceFieldName" : "metadata_spo_site_library_item_id", 
          "targetFieldName" : "id", 
          "mappingFunction" : { 
            "name" : "base64Encode" 
          } 
         }
    ]
}

I follow the usual Auth, that all works fine no problem, after that I get the following error and I'm not sure what to do with it.

apiError - Failed to update indexer "sharepoint-indexer", error: "Error with data source: Unexpected SharePoint library path 'https://[INSERT COMPANY HERE].sharepoint/sites/GCHighlines/Shared%20Documents/Forms/AllItems.aspx?id=%2Fsites%2FAGCHighlines%2FShared%20Documents%2FEditing%20Highlines%2FBROO'. Please provide a valid SharePoint library path. Please adjust your data source definition in order to proceed."

Any thoughts on how to proceed or correct this? I'd like to limit the number of times I get the admin access from my boss hahaha
