I am making one shell script that helps me to copy all my assets to the dist folder but I am facing weird issue while doing this

Code

extensions=("json" "pug")

printf -v text '**/*.%s ' "${extensions[@]}"
echo $text

I am getting: locales/de.json locales/en.json views/error.pug views/layout.pug

I want: **/*.json **/*.pug

My need

I want to copy all my json and pug files into my dist folder and I am using copyfiles npm package to fullfil my need.

I want an array so if in future I want to add one another extension then I can add it easily, my goal is to write copyfiles **/*.json **/*.pug dist

My script

#!/bin/bash

extensions=("json" "pug")
folderName="dist"

rm -rf ./$folderName
echo "Removed $folderName folder"

echo "Build started"
tsc --project tsconfig.json
echo "Build ready"

printf -v text '**/*.%s ' "${extensions[@]}"
copyfiles "$text" $folderName
echo "Extensions added into $folderName"

I am executing this script with bash -e ./build.sh
