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

I tried that, does not works

I have this as filter

Vijayalakshmi_S

using command

mvn clean install -PautoInstallPackage

Since it is your local instance, delete the bundle manually from this path - /apps/yourproject/install/yourproject.core-0.0.1-SNAPSHOT.jar in CRXDE and then trigger the deployment again.

(Provided core module is enabled and bundle is getting created successfully as part of the build process)

Just dealing with the same error here, I came around this article that may be helpful:
