cannot deploy to docker - failing on cryptography and Can not find Rust compiler

Question

I am trying to deploy a new version on docker but I have an error that I have not seen before. I followed steps to install cryptography and upgrade pip but this did not work. PLEASE let me know if anyone has an idea on how to fix this. THANK YOU!
