In a React component, reset the global error flag within the `finally` block of your `fetch` or `axios` call's `.then()` and `.catch()` chain. This ensures the flag is reset regardless of success or failure. Alternatively, use `async/await` with a `try...finally` block for cleaner code. Example: `try { const response = await fetch(...); } catch (error) { // handle error } finally { setGlobalErrorFlag(false); }` where `setGlobalErrorFlag` updates the global state.
