Changing path to current working directory in zsh prompt - zsh

Question

I'm trying to modify an existing zsh prompt to work with zsh 5.0 and 4.3 because those the versions the systems that I use. How would I make a zsh-script be aware of the current working directory instead of the directory that the file is in?
For context,
This is a function in the script that checks if we're currently in a git directory and adds to the prompt if we are:
# Git status.
# Collect indicators, git branch and pring string.
spaceship_git_status() {
[[ $SPACESHIP_GIT_SHOW == false ]] && return
# Check if the current directory is in a Git repository.
command git rev-parse --is-inside-work-tree &>/dev/null || return
# Check if the current directory is in .git before running git checks.
if [[ "$(git rev-parse --is-inside-git-dir 2> /dev/null)" == 'false' ]]; then
# Ensure the index is up to date.
git update-index --really-refresh -q &>/dev/null
# String of indicators
local indicators=''
indicators+="$(spaceship_git_uncomitted)"
indicators+="$(spaceship_git_unstaged)"
indicators+="$(spaceship_git_untracked)"
indicators+="$(spaceship_git_stashed)"
indicators+="$(spaceship_git_unpushed_unpulled)"
[ -n "${indicators}" ] && indicators=" [${indicators}]";
echo -n " %Bon%b "
echo -n "%{$fg_bold[magenta]%}"
echo -n "$(git_current_branch)"
echo -n "%{$reset_color%}"
echo -n "%{$fg_bold[red]%}"
echo -n "$indicators"
echo -n "%{$reset_color%}"
fi
}
However, based on my debugging, it appears that the function always believes that it is in the directory from which the script was sourced. In other words, as I change directory, the script continues to reference the directory where the script is located.
The spaceship_git_status function is called here:
# Build prompt line
spaceship_build_prompt() {
spaceship_host
spaceship_current_dir
spaceship_git_status
spaceship_nvm_status
spaceship_ruby_version
spaceship_venv_status
}
And this is the PROMPT environment variable is:
# Compose PROMPT
PROMPT=''
[[ $SPACESHIP_PROMPT_ADD_NEWLINE == true ]] && PROMPT="$PROMPT$NEWLINE"
PROMPT="$PROMPT $(spaceship_build_prompt) "
[[ $SPACESHIP_PROMPT_SEPARATE_LINE == true ]] && PROMPT="$PROMPT$NEWLINE"
PROMPT="$PROMPT $(spaceship_return_status) "
I think this is an issue with zsh versions < 5.2 because the prompt renders fine on my other computer with 5.2.
