I'm trying to built an automatic deployment pipeline for an application and I have some problems with `amplify add hosting`. The script is asking to choose between DEV and PROD (using arrow keys) and then asks for the bucket name and endpoints (index.html)

I'm deploying from an Ubuntu 18.04 and I successfully inejcted the DOWN arrow key to select the prod value but after that, the script is not reading anymore :

`echo -e "\033[B" | amplify add hosting` will select PROD, but will crash immediately since EOF is sent.
I tried adding other stuff after like so :
`echo -e "\033[B\nbucketname"` and the script just crashes

If I try to input all the values asked and I have the same result :


Are there any options that I missed for sending values as arguments and preventing the console to ask to manually set the values (I tried to use the --yes option but obviously it was not working).
