Using the CreateXYEventLayer tool

Question

I'm trying to use the "CreateXYEventLayer" tool to create a point event layer from a .csv file. It works when I use the tool from within the project, but when I try to do it via the SDK (with the same .csv file), it fails. Is something wrong with my parameters or the way that I am executing the tool? P.S. I'm very new to the ArcGIS SDK. Thanks in advance! Here is the code:

public async Task CreatePointEventLayerFromCsv(string csvPath)
{
     var parameters = Geoprocessing.MakeValueArray(
                                  csvPath,
                                  "X",
                                  "Y",
                                  "NewEventLayer",
                                  SpatialReferenceBuilder.CreateSpatialReference(4326)
     );
     var result = await QueuedTask.Run(() =>
     {
          return Geoprocessing.ExecuteToolAsync("CreateXYEventLayer_management", parameters);
     });

if (result.IsFailed)
     {
          MessageBox.Show("Failed to create point event layer from CSV");
     }
     else
     {
          MessageBox.Show("Success");
     }
}

Make sure your CSV is:

* Accessible from ArcGIS Pro (e.g., absolute path).

* Compliant with ArcGIS standards (e.g., no mixed datatypes in fields).

* Ideally added to the map or project — sometimes tools resolve better when it’s registered.

public async Task CreatePointEventLayerFromCsv(string csvPath)
{
    // Ensure the path is valid and the CSV is accessible
    if (!File.Exists(csvPath))
    {
        MessageBox.Show("CSV file not found.");
        return;
    }

var parameters = Geoprocessing.MakeValueArray(
        csvPath,                         // Input Table
        "X",                             // X Field
        "Y",                             // Y Field
        "xy_layer",                      // Layer Name (not a path)
        SpatialReferenceBuilder.CreateSpatialReference(4326) // WGS84
    );

// Run tool
    var environments = Geoprocessing.MakeEnvironmentArray(overwriteoutput: true);

var result = await Geoprocessing.ExecuteToolAsync(
        "CreateXYEventLayer_management",
        parameters,
        environments,
        null,
        null,
        GPExecuteToolFlags.Default
    );

if (result.IsFailed)
    {
        MessageBox.Show("Failed to create point event layer from CSV:
" + result.ErrorMessages);
    }
    else
    {
        MessageBox.Show("Success");
    }
}

Hello @LandonPrince , please can you describe a bit more about what happens when it "fails". Perhaps post some screenshots or other details.
