Fix

The "context deadline exceeded" error occurs because your code waited longer than the specified timeout for an operation to complete. Increase the timeout duration or optimize the slow operation to finish within the limit.

ctx, cancel := context.WithTimeout(context.Background(), 30*time.Second)
defer cancel()

// Use ctx in your function calls
result, err := slowOperation(ctx)
if err == context.DeadlineExceeded {
    // Handle timeout
}

The "context deadline exceeded" error in Go means your program gave up waiting for a task to finish because it took too long. It's like waiting for a bus that never arrives, so you leave before the maximum wait time expires. You fix it by either waiting longer or making the task faster.
