Bash Build Whoas

build.sh

#!/usr/bin/env bash
set -eu

declare -a build_projects=('./src/My.Extensions.ApiVersioning/')
declare -a test_projects=('./tests/IntegrationTests/' './tests/UnitTests/')

pwsh -NoProfile -ExecutionPolicy Bypass -Command "& '.\build.ps1' -projects " "${build_projects[@]}" "-tests " "${test_projects[@]}"

if [ $# -ne 0 ]; then
  echo "Failed to build."
  exit 1
fi

echo "Successfully built project."
exit 0

buils.ps1

param(
    [string[]] $projects,
    [string[]] $tests
)


Write-Host "Testing projects."
foreach ($test in $tests) {
    Write-Host $test
} 

Why does only the first item in the array get passed?
