Servlet Calls 204 error in AEM 6.5

[#1]

Hi All,

After upgrading to aem 6.5.6(inplace from 6.4.8.1.to 6.5.6) i am facing with POST and DELETE calls are going to 204 instead of 302 or 200.

Please let me know if any came across this issue.

Thanks

Can you please add more details to this? Which POST requests exactly? What servlets are you hitting? What's going in the error.log?

I think youll need to investigate more. Does this happen on your local dev? Does this happen if you hit your custom servlet directly on AEM (vs. going through dispatcher)? What is the Request Progress log for this request (available in OSGi console)? Does your custom servlet have any code that could return a 204 response?

Can you expand a bit more when you say 'accessing through the application'? Is there a 3rd party or external system that is trying to access and consume data from AEM? HTTP 204 response = 'no content', which is what I would expect to get back from a successful preflight request from an outside application. Just curious if this is a possible CORS issue.
