When testing the API server, you may run into errors with ACB error codes. 

These errors are explained through the "message" portion. 

If you would like to check all the error codes they are located in the following file: 

C:\Program Files\BioStar 2 API Server(x64)\dist\apps\lib\message_handler\resources\messages_en.properties

Attached is the messages_en.properties file based on API Server 2.6.0
