When trying to run `brew tap scaleway/scaleway`: undefined method `cellar'

[finicu212]

Hi, I'm trying to install this via brew, however it says there is an invalid method cellar (Invalid syntax in tap!):

$ brew tap scaleway/scaleway

Warning: DEPRECATED: This is the last version released with this formula.
Please uninstall this version and use the official formula: brew uninstall -f scw && brew install scw

Error: Invalid formula: /home/linuxbrew/.linuxbrew/Homebrew/Library/Taps/scaleway/homebrew-scaleway/scw.rb
scw: undefined method `cellar' for #<BottleSpecification:0x00000000038c0138>
Error: Cannot tap scaleway/scaleway: invalid syntax in tap!

installing the CLI tool (scw) however works fine but that is in homebrew/core
