find (fd) execute with custom function and multiple parameters

Question

I'm quite new to bash scripting so excuse the rough script. I'm writing a simple script that goes through all directories that has a .git directory in them, and checks if the worktree is clean or dirty. It works, but I want to have 3 parameters:

rootDir: top level directory to search for .git directories.
status: clean|dirty|all which will filter the output based on the status of the direcotries
separator: Allows passing null which would do a \0 separator so that I can pass this output to xargs and further run commands while supporting paths with spaces.

The problem I'm facing is with passing parameters from the fd exec to my isRepoDirty function. The $cleanOrDirty parameter somehow makes it in, but the $separator parameter doesn't work. My single quote, double quote knowledge is a bit shaky here... If I have my params inside the single quotes, they never get expanded.

Here is what I have:

#!/bin/bash
# DOES NOT WORK IN ZSH!
# https://unix.stackexchange.com/questions/50692/executing-user-defined-function-in-a-find-exec-call

rootDir=$1
cleanOrDirty=$2
separator=$3

# echo "Root: $rootDir"
# echo "Clean or Dirty: $cleanOrDirty"
# echo "Separator: $separator"

function isRepoDirty() {
    if [[ $(git --git-dir "$1" --work-tree "$1/.." status --porcelain | wc -l) > 0 ]]; then
        status="dirty"
    else
        status="clean"
    fi

    # echo "Repo: $1, Status: $status"
    if [[ $2 == $status || $2 == "all" ]]; then
        # echo "Separator: $3"
        if [[ $3 == "null" ]]; then
            printf "%b" "$1/..\0"
        else
            echo "$1/.."
        fi
    fi
}
export -f isRepoDirty

fd --no-ignore --hidden -t d "\.git$" $rootDir -x /bin/bash -c 'isRepoDirty "{}" '$cleanOrDirty $separator

If my approach to this is totally off, please do tell me as I'm quit keen to learn and do what's considered best practise. Heh my passing of args is a bit rudimentary. I haven't found a simple way to easily handle -p and --parameter-name style arguments easily in bash.

Thanks for your time!
