  Problem 1
    - Installation request for botman/driver-facebook ^1.2 -> satisfiable by botman/driver-facebook[1.2.0].
    - Conclusion: don't install botman/botman 2.1.2
    - Can only install one of: botman/botman[2.1.0, 2.0.1].
    - Can only install one of: botman/botman[2.1.0, 2.0.1].
    - Can only install one of: botman/botman[2.1.0, 2.0.1].
    - botman/driver-facebook 1.2.0 requires botman/botman ~2.1 -> satisfiable by botman/botman[2.1.0, 2.1.1, 2.1.2].
    - Conclusion: don't install botman/botman 2.1.1
    - Installation request for botman/botman (locked at 2.0.1, required as ~2.0) -> satisfiable by botman/botman[2.0.1].

Installation failed, reverting ./composer.json to its original content.

Successfully installed driver "Facebook"

update your botman version in composer.json to version ~2.1

"botman/botman": "~2.0", => "botman/botman": "~2.1",

then run composer update botman/botman

This fixed my issue.
