I hope you're trying to call the servlet from AEM itself, did you try by removing localhost:4502 and just use something like post('/bin/login', fromData) and see how it works.

Can you try this and see if it works:

http://localhost:4502/system/console/components
Go to "Apache Sling Referrer Filter"
Select "Allow Empty"

If your requests are getting blocked, this should fix it.

- Please check if you have implemented SlingHttpSafeServlet or AllMethodServlet in your servlet.

- Try to call the same servlet through Postman and see if it is working fine

Looks like your servlet is not available in the instance at first place.

3581 TIMER_END{285,ResourceResolution} URI=/bin/my/login resolves to Resource=NonExistingResource, path=/bin/my/login
3597 LOG Resource Path Info: SlingRequestPathInfo: path='/bin/my/login', selectorString='null', extension='null', suffix='null'
3598 TIMER_START{ServletResolution}
3605 TIMER_START{resolveServlet(/bin/my/login)}
5260 LOG {0}: no servlet found

Cross check the deployment and see if you are able to see the servlet in

http://localhost:4502/system/console/components and is active

or

http://localhost:4502/system/console/servletresolver Enter the servlet path and choose the method to be POST and see if it resolves to your servlet.

I did not found it in http://localhost:4502/system/console/components

what does that mean 🙂 😅
