☔ Cause of error

👉 I'll pretend I didn't see your mistake :)

Maybe you made the announcement as below.

@RestController is intended to avoid declaring @ResponseBody in each function.
@RestController is a combination of @Controller and @ResponseBody.

🧙 Solution

👉 If you use @RestController, please delete the @ResponseBody announcement.
