Postman ошибка 404

I have updated the POSTMAN to the latest version. When I hit the Update option I get ‘You are up to date! Postman v6.0.10 is the latest version.’

I have been successful to send a POST from my another POSTMAN and able to get the correct response. However, I have been running into an issue when sending a POST method to the same API from my POSTMAN. Does not seem to be a routing issue, as it works with another client.
Is it related to any configuration problem or any setting that I need to configure from POSTMAN end?

Been struct into this for some time now, with no clue. Any helps would be greatly appreciated!

Following is the curl command:
curl -X GET
http://SERVER/endpoint/endpoint/ID/endpoint
-H ‘Authorization: bearer ‘
-H ‘Cache-Control: no-cache’
-H ‘Content-Type: application/....***+json’ OR application/json
-H ‘Postman-Token: ac11bb07-3v4f-411b-a712-g6f8c6a74781’
-d ‘{
«user»: «user1»,
«description»: «Test Action»,
«mandatory»: true
}’

I am currently working on a small personal project(springboot + MYSQL), in that while testing in POSTMAN , its showing 404 resource not found .

NOTE: both application and MYSQL is running successfully without any problem and POSTMAN is working properly.

controller is fine as of my knowledge.

where is the problem in code? kindly help me out.

I tried to test in POSTMAN ,but its showing 404 error .

NOTE: postman is working properly ,i have checked by testing another application.

what the problem in the code ? where to look out for in the application

when i hit http://localhost:8081/user/signup , i am getting 404

Solution 1

HTTP 404 is returned when the server is unable to find method to match your exact request.

For the mentioned request have the url as http://<context>/requestpath with request method as POST.(http://localhost:8080/person)

Check the request body and all the fields should exactly match the Person object else it may return HTPP 400.

Solution 2

In My Case it was simple mistake and spend an hour for figuring it out that i had space at the end of my url.
