login method does not work for http rest api v4_1 using SuiteCRM 8.7.1, PHP 8.2.26

[DavidGalicia]

Issue

When I call the login api method with the data that url percent encodes:

{
  "method": "login",
  "input_type": "JSON",
  "response_type": "JSON",
  "rest_data": "{\"user_auth\":{\"user_name\":\"api_user\",\"password\":\"a5a655a79dfd80008fea647a98c14ce7\"},\"application_name\":\"api-client\"}"
}

The server responds with an http 500 error status and does not return a session_id. On the server, I see the following error in /var/log/apache2/error.log:

[Tue Dec 17 14:01:49.212696 2024] [php:error] [pid 981:tid 981] [client 192.168.113.4:52174] PHP Fatal error:  Cannot declare class LanguageManager, because the name is already in use in /var/www/html/public/legacy/include/SugarObjects/LanguageManager.php on line 50

Possible Fix

To make the login method work and return a session_id I needed to fix the class re-declaration errors in /public/legacy/include/entryPoint.php and json decoding errors in /public/legacy/include/utils.php when clean_incoming_data() processes http rest api request data.

The changes are in the code fork here.

Steps to Reproduce the Issue

1. Call the `login` method of the v4_1 api
2. Check `/var/log/apache2/error.log` for errors
