Undefined constant Flutterwave\Config\PackageConfig::BASE_URL

[Corneille9]

Description

When attempting to verify a transaction using the verifyWithTxref() method in the flutterwavedev/flutterwave-v3 package, an error occurs indicating "Undefined constant Flutterwave\Config\PackageConfig::BASE_URL". This issue arises during the initialization of the Transactions service.

Steps to Reproduce

1. Initialize the Transactions service with the appropriate configuration using the following code:

   $transaction = new \Flutterwave\Service\Transactions(
       PackageConfig::setUp(
           ……,
           ……,
           ……,
       )
   );
   

2. Attempt to verify the transaction using the verifyWithTxref($id) method.

Expected behaviour

The Transactions service should initialize successfully.

Actual behaviour

The error "Undefined constant Flutterwave\Config\PackageConfig::BASE_URL" occurs during the initialization of the Transactions service, specifically in the constructor at line 34: $this->baseUrl = $this->config::BASE_URL.

Configuration

• API Version: v3
• Environment: live
• Language: PHP 8.1 | Laravel 10.10

Additional Information

The issue seems to stem from the constructor of the \Flutterwave\Service\Transactions class. The line $this->baseUrl = $this->config::BASE_URL attempts to access the constant BASE_URL from PackageConfig, resulting in an undefined constant error.
