Spring Boot REST API returns 404 on POST

I'm building a REST API with Spring Boot and I have a controller for handling tasks. When I try to send a POST request to /tasks using Postman, I get a 404 Method Not Allowed error.

My goal is to send a JSON body to create a new task. I expect POST /tasks to be routed to the createTask() method in my controller, but it doesn't work. Other methods doesnt work also though im not sure

main class with @SpringBootApplication:

@SpringBootApplication
public class ToDoManagerApplication {
    public static void main(String[] args) {
        SpringApplication.run(ToDoManagerApplication.class, args);
    }

My TaskController class

package az.edu.turing.todomanager.controller;
import az.edu.turing.todomanager.model.Task;
import az.edu.turing.todomanager.service.TaskService;
import lombok.RequiredArgsConstructor;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.*;
import java.util.List;

@RestController



public class TaskController {

    private final TaskService taskService;

    public TaskController(TaskService taskService) {
        this.taskService = taskService;
        System.out.println("taskcontroller init");
    }


    @GetMapping
    public List<Task> getAllTasks(){
        return taskService.getAllTasks();

    }

    @GetMapping("/{id}")
    public ResponseEntity<Task> getTaskById(@PathVariable Long id) {
        return taskService.getTaskById(id)
                .map(ResponseEntity::ok)
                .orElse(ResponseEntity.notFound().build());
    }

    @PostMapping
    public Task createTask(@RequestBody Task task){
        return taskService.createTask(task);

}
    @PutMapping("/{id}")
    public ResponseEntity<Task> updateTask(@PathVariable Long id, @RequestBody Task updatedTask) {
        try {
            Task task = taskService.updateTask(id, updatedTask);
            return ResponseEntity.ok(task);
        } catch (RuntimeException e) {
            return ResponseEntity.notFound().build();
        }
    }
    @DeleteMapping("/{id}")
    public ResponseEntity<Void> deleteTask(@PathVariable Long id) {
        taskService.deleteTask(id);
        return ResponseEntity.noContent().build();
    }

}

My TaskServiceImpl class:

package az.edu.turing.todomanager.service.impl;

import az.edu.turing.todomanager.model.Task;
import az.edu.turing.todomanager.repository.TaskRepository;
import az.edu.turing.todomanager.service.TaskService;
import lombok.RequiredArgsConstructor;
import org.springframework.stereotype.Service;

import java.util.List;
import java.util.Optional;

@Service
@RequiredArgsConstructor
public class TaskServiceImpl implements TaskService{
    private final TaskRepository taskRepository;

    @Override
    public List<Task> getAllTasks() {
        return taskRepository.findAll();
    }

    @Override
    public Task createTask(Task task) {

        return taskRepository.save(task);
    }

    @Override
    public Optional<Task> getTaskById(long taskId) {
        return taskRepository.findById(taskId);
    }

    @Override
    public Task updateTask(Long taskId, Task updatedTask) {
        return taskRepository.findById(taskId)
                .map(existingTask -> {
                    existingTask.setName(updatedTask.getName());
                    existingTask.setDueDate(updatedTask.getDueDate());
                    existingTask.setStatus(updatedTask.getStatus());
                    return taskRepository.save(existingTask);
                })
                .orElseThrow(() -> new RuntimeException("Task not found with id: " + taskId));
    }

    @Override
    public void deleteTask(Long taskId) {
        taskRepository.deleteById(taskId);

    }


}

My application.properties:

spring.application.name=to-do-manager
spring.datasource.url=jdbc:postgresql://localhost:5432/todomanager
spring.datasource.username=postgres
spring.datasource.password=mypassword

spring.jpa.hibernate.ddl-auto=update
spring.jpa.show-sql=true
spring.datasource.driver-class-name=org.postgresql.Driver
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.PostgreSQLDialect
management.endpoints.web.exposure.include=*

I have Verified URL and method in Postman

Added @RequestMapping("/tasks") at class level

Confirmed controller is initialized

Restarted app multiple times , but still either 405 or 404 error,

http://localhost:8080/tasks-----> POST---> 404 error http://localhost:8080/todomanager/tasks------> 404 error
