+
+Error Handling:
+If an incorrect parser function is chosen, an errParse will be returned. Here's an example using ToArray which demonstrates this scenario:
+
+```golang
+// Attempt to parse the response. If a parsing error occurs, check if the error is a parse error and handle it.
+// Normally, you should fix the code by choosing the correct parser function.
+// For instance, use ToString() if the expected response is a string, or ToArray() if the expected response is an array as follows:
+if err := client.Do(ctx, client.B().Get().Key("k").Build()).ToArray(); IsParseErr(err) {
+    fmt.Println("Parsing error:", err)
+}
+```
 
 It is hard to remember what type of message will be returned and which parsing to use. So, here are some common examples:
