Mos put error: port not chosen

If you are asking a question, please follow this template:

  1. My goal is: upload init.js to the device
  2. My actions are: i execute “mos put fs/init.js” by following this “guide”
    https://mongoose-os.com/docs/mongoose-os/cloud/aws.md
    the part of " Reporting metrics to AWS IoT"
  3. The result I see is: “Port not chosen” (in red)
  4. My expectation & question is: the execution of mos put without errors

if you see how to “choose” the port for mos put command, please tell me where. in my experience learning mongoose os there are a big lack of basic information like this in all the documentation. it is very annoying learning where all the guides are outdated and there is no list of commands and options.

please help me. thank you!
