ASP.NET Core API sending double quoted string

Question

My ASP.NET Core API generates SASfor a file to be uploaded to Azure Blob storage. It looks like the string is wrapped in double quotes, and this creates a problem with the front-end solution that I use to upload files.

How can I return a string but not wrap it in double quotes?

This is the API controller:

public async Task<IActionResult> GetSAS(string blobUri, string _method)
{
    if (string.IsNullOrEmpty(blobUri) || string.IsNullOrEmpty(_method))
       return new StatusCodeResult(400);

    // Get SAS
    var sas = _fileServices.GetSAS(blobUri, _method);

    return Ok(sas);
}
