php - Users and channels are not getting created when executed inside Paypal IPN

Question

Issue Summary

I implemented Twilio chat service for my CodeIgniter 3 application. I added a new method and called it from Paypal IPN which will create two types of users and a private channel for one-to-one communication.

Strangely, after executing few lines of that method, execution is getting stopped. It's happening when the Paypal IPN is hit for the first time. But next time, when I make a payment and the IPN is hit again, all the code is working properly.

Recently updated to the latest version of twilio-php but the issue remains. Not sure whether I'm doing something wrong. Please suggest a solution for this.

Code Snippet

// Paypal IPN
public function paypal_ipn() {
   ...............[code]...............
   if ($this->makeChatKitRelation($check_relation_exists['company_id'], $check_relation_exists['job_seeker_id'], $check_relation_exists['channel_id'])) {
        // 1. Not entering inside this as (see comment 2 below)
        $update_data = array(
            'number_allowed' => $check_chat_allowed_count->number_allowed + $packageDetails["num_careerseeker_contact_allowed"],
            'already_availed' => $check_chat_allowed_count->already_availed + 1,
        );      
        $this->Company_career_seeker_contact_allowed_model->updateChatAllowedCount($update_data, $check_relation_exists['company_id']);
    }
    die;
}

// Function used to make chat users & channels

  $companyDetails = $this->Companybasic_model->checkChatKitStatus($companyId); // fetch user details from DB (if user doesn't exists in twilio)
