Using RestSharp to request a file fails with memory issue

I have to API's talking to each other on Kubernetes. The first API asks the second API for a small file using RestSharp (in ASP.NET). The file is 8Kb so basically not large at all.

Yet i get the following message on the API that wants to receive the file:

Exception of type 'System.OutOfMemoryException' was thrown.
   at RestSharp.RestClient.ThrowIfError(RestResponse response)
   at RestSharp.RestClientExtensions.GetAsync(RestClient client, RestRequest request, CancellationToken cancellationToken)
   at Aftermarket.Server.AdministrationService.Server.Services.Services.RunSessionService.DownloadRunSession(String foldername) in /src/Aftermarket.Server.DbApi/Server/Services/Services/RunSessionService.cs:line 59
 

The code U use to call the other API and ask for the file looks as follows:

 public async Task<byte[]> DownloadRunSession(string foldername)
 {
    try
    {
     var request = new RestRequest($"{config["WebApiServer:WebApiServerUrl"]}/blob/{foldername}");

     var response = await client.GetAsync(request);

      if (!response.IsSuccessful)
      {
      Console.WriteLine("File download failed");
      Console.WriteLine(response.StatusCode);
                    
      return null;
      }

      return response.RawBytes;

      }catch(Exception e)
     {
        Console.WriteLine(e.Message);
        Console.WriteLine(e.StackTrace);
        return null;
     }
}

The API that responds by sending the file has the following controller method:

public IActionResult GetBlob([FromQuery] string folderName, [FromServices] GetBlobsService _getBlobsService)
{
  _logger.Info(folderName);
  Guid guid = Guid.NewGuid();

  if (_env.EnvironmentName == "dev" || _env.EnvironmentName == "prod")
  {
    byte[] blob = _getBlobsService.GetBlob(folderName, guid, _logger);

    if (blob == null)
    return this.NotFound();
    else
    {
      return File(blob, "application/force-download", guid + ".zip");
    }
        }
            else
            { return Content("This function is only available in Dev/Uat Environment"); }
        }

Any one have any idea how a 8Kb file is causing this issue?
