The return type should be ResponseEntity<SuccessResponse<?>> but SuccessResponse.ok() likely returns SuccessResponse<?>. You need to wrap it with ResponseEntity.ok() to match the method signature: return ResponseEntity.ok(SuccessResponse.ok(changeRequests));

Suggested change

	return SuccessResponse.ok(changeRequests);
	return ResponseEntity.ok(SuccessResponse.ok(changeRequests));
