Relational Databases - Build a Salon

Could someone have a look over my salon.sh please?
Screenshots below appear to suggest that the script is behaving as expected (with expected sample output on right), and the database is being updated accordingly, but the tests below are not passing… (all others are passing).
Maybe I’m missing something obvious?

#!/bin/bash

PSQL="psql -X --username=freecodecamp --dbname=salon --tuples-only -c"

echo -e "\n~~~~~ MY SALON ~~~~~\n"
echo -e "\nWelcome to My Salon, how can I help you?\n"

SERVICE_MENU() {

  if [[ $1 ]]
  then
    echo -e "\n$1\n"
  fi

  #get services
  SERVICES=$($PSQL "SELECT * FROM services ORDER BY service_id")

  echo -e "$SERVICES" | while read SERVICE_ID BAR SERVICE
  do
   echo "$SERVICE_ID) $SERVICE"
  done

  read SERVICE_ID_SELECTED
  if [[ ! $SERVICE_ID_SELECTED =~ ^[0-9]+$ ]]
  then
    SERVICE_MENU "I could not find that service. What would you like today?"
  else
    
    SERVICE_NAME=$($PSQL "SELECT name FROM services WHERE service_id=$SERVICE_ID_SELECTED")
  
    #check if valid service_id
    if [[ -z $SERVICE_NAME ]]
    then
      SERVICE_MENU "I could not find that service. What would you like today?"
    else
      #get customer info
      echo -e "\nWhat's your phone number?"
      read CUSTOMER_PHONE
      CUSTOMER_NAME=$($PSQL "SELECT name FROM customers WHERE phone = '$CUSTOMER_PHONE'")

      # if customer doesn't exist
      if [[ -z $CUSTOMER_NAME ]]
      then
        # get new customer name
        echo -e "\nI don't have a record for that phone number, what's your name?"
        read CUSTOMER_NAME

        # insert new customer
        INSERT_CUSTOMER_RESULT=$($PSQL "INSERT INTO customers(name, phone) VALUES('$CUSTOMER_NAME', '$CUSTOMER_PHONE')") 
      fi

      # get customer_id
      CUSTOMER_ID=$($PSQL "SELECT customer_id FROM customers WHERE phone='$CUSTOMER_PHONE'")

      # ask appointment time
      echo -e "\nWhat time would you like your $(echo $SERVICE_NAME | sed -r 's/^ *| *$//g'), $(echo $CUSTOMER_NAME | sed -r 's/^ *| *$//g')?"
      #check time format
      while [[ ! $SERVICE_TIME =~ ^([0-9]{2}\:[0-9]{2})$ ]]
      do
      echo -e "\nPlease enter time in format hh:mm"
      read SERVICE_TIME
      done
      #if valid insert into appointments table
      INSERT_APPOINTMENT=$($PSQL "INSERT INTO appointments(customer_id, service_id, time) VALUES($CUSTOMER_ID, $SERVICE_ID_SELECTED, '$SERVICE_TIME')")
      echo -e "\nI have put you down for a $(echo $SERVICE_NAME | sed -r 's/^ *| *$//g') at $(echo $SERVICE_TIME | sed -r 's/^ *| *$//g'), $(echo $CUSTOMER_NAME | sed -r 's/^ *| *$//g')."
    fi  
  fi
}

SERVICE_MENU



Should you share the dump of the db as well?
