How to read multiple Publisher objects from publish response and write PUBLISHER_N in .env file

publish.sh

# Get a space-separated string of publisher object IDs
PUBLISHER_IDS_STRING=$(echo "$newObjs" | jq -r 'select(.objectType | contains("::Publisher")).objectId')

# Read the Publishers string into an array using a while loop
declare -a PUBLISHERS
while IFS= read -r line; do
    PUBLISHERS+=("$line")
done <<< "$PUBLISHER_IDS_STRING"

# Create a temporary file to hold the environment variables
temp_env=$(mktemp ./temp_env)

# Iterate over the array and write each publisher ID to the temporary file
for i in "${!PUBLISHERS[@]}"; do
  echo "PUBLISHER_$((i + 1))=${PUBLISHERS[i]}" >> "$temp_env"
done

{
  # rest of environment variables
  cat "$temp_env"  # This line will add the PUBLISHER_n variables to the .env file
  # rest of environment variables
} > .env

# Clean up the temporary file
rm "$temp_env"
