fatal error on macOS w bash

When I try to source avn with . ~/.avn/bin/avn.sh, I get the following error:

Fatal Error: Cannot find module '/Users/someuser/.avn/plugins/avn-nvm'

My steps:

npm install -g avn avn-nvm avn-n 2 avn setup which adds config to $HOME/.zshrc despite current shell as bash
add same configuration to $HOME/.bashrc and launch new terminal tab
cd to project with .node-version, version doesn't change
attempt to source in current shell directly with . ~/.avn/bin/avn.sh and get a fatal error.

Details

avn avn --version: 0.2.4
node node --version: v18.4.0
nvm nvm --version: 0.39.3
n n --version: n/a
zsh zsh --version: zsh 5.9 (arm-apple-darwin21.3.0)
bash bash --version: GNU bash, version 5.2.15(1)-release (aarch64-apple-darwin21.6.0)

The output of __avn_debug in the directory with a .node-version file is:

# n/a as do not get this far

avn is loaded in my ~/.{bash|zsh}{_profile|rc} file with:

[[ -s "$HOME/.avn/bin/avn.sh" ]] && source "$HOME/.avn/bin/avn.sh" # load avn

nvm specific

[ ] As an nvm user I am confirming that I did not install with Homebrew
