This is the error I get in postman -
{
"timestamp": "2023-02-03T10:33:58.409+00:00",
"status": 404,
"error": "Not Found",
"path": "/employee/all"
}
I am trying to use the endpoint http://localhost:8080/employee/all
Please let me know if you know why postman is not able to find this end point.
I have tried some ways for this issue on the internet but cannot debug it.
