ID: PM-31688

[mphillippiAPG]

just as with #6689, the error can be worked around by adding the alias such as to your .zshrc or .bashrc (or the like):

alias bw='NODE_OPTIONS="--no-deprecation" bw'

or adding an export in your .zshrc or .bashrc if you want to just blanket no deprecation messages in node like:

export NODE_OPTIONS="--no-deprecation"

or preface the command bw command each time like:

NODE_OPTIONS="--no-deprecation" bw <arg>
