Status Code: 204 No Content

Hello,

my store running on Magento 2
I am using Stape Server Side extesion for magento 2
As soon as i started using it, i notice a csp violation

The following were blocked
https://region1.analytics.google.com
https://region1.google-analytics.com

I added them to csp_whitelist.xml and now, at google chrome Network i see
that register-conversion?_c gives a Status Code: 204 No Content.

What does it means?
Is still blocked?
The data are blocked?

Does anyone knows something about it?

What should do about it?

On which request do you see a 204 status? If GA this is normal behaviour.
