Difficult debugging due to opaque abstraction layers
7/10 HighDebugging in LangChain is challenging because abstraction layers hide underlying complexity. Tracing errors through nested chains with multiple steps is arduous, and granular logging is limited, making troubleshooting time-consuming.

Collection History
The abstraction layer that made development feel fast initially became an opaque wall when things went wrong on a specific device or OS version. Solving these issues required deep native knowledge of both iOS and Android.
Asynchronous programming is a fundamental aspect of JavaScript, especially when dealing with APIs or web requests. However, callbacks and promises can lead to complex, hard-to-debug code
Debugging in LangChain is difficult due to the layered nature of the chains and limited granular logging. Debugging agents and chains can sometimes be non-trivial, especially when errors are deep in nested components.
