Hello,

Does anyone know what I am doing wrong or what wrong with [https://flows.nodered.org/node/node-red-contrib-cos](https://flows.nodered.org/node/node-red-contrib-cos)? It seems that no matter what I set the Content Type to the object is set to `application/octet-stream` when uploaded by Node Red.
