Resolving Fetch Blocking Issues in React Native Applications

The Issue

After using my React Native application for a while, I suddenly encountered a problem where all fetch API calls became blocked. Through investigation, I discovered that the root cause was related to having multiple API calls that were not receiving responses. When these unresolved API requests accumulated, they eventually caused a complete blockage of all subsequent network requests in the application.

The Solution

I resolved this issue by identifying and fixing the problematic API endpoints that weren't returning proper responses. By ensuring that all API calls either successfully completed or properly timed out with appropriate error handling, I was able to prevent the accumulation of pending requests. This fix restored normal functionality to the application's networking capabilities. This experience highlights the importance of implementing proper timeout handling and error recovery for all network requests in React Native applications to prevent cascading failures in the app's communication with backend services.
