PRODUCT: 4D | VERSION: 20 R9 | PLATFORM: Mac & Win
Published On: September 29, 2025

In any complex application, various types of errors are bound to occur, from missing files and unstable network connections to unexpected bugs. These errors generally fall into several categories: syntax errors, which result from that violates the languageās rules and are typically caught at compile time, runtime errors, which arise during execution due to invalid operations like division by zero, logical errors, which produce incorrect results despite the program running smoothly, network errors, caused by connectivity issues such as timeouts or unreachable servers, and resource errors, which occur when the system runs out of memory or file handles.
Modern 4D development tools offer robust solutions to detect, analyze, and manage these errors efficiently. By integrating such tools, developers can facilitate diagnostics, maintain application stability, and ensure a seamless user experience.
