Disable Hit for Cache not working

I try to disable the cache in the JS package by new CacheOverride("pass") and by configuration in the deliver service.
In addition I tried to add VCL snippet to redirect vcl_hit to “pass”.
do you know about any bug in Fastly side?

You can do that in both VCL and JS services. See this:

usually it is working. but now it is not working.
Are you sure no bug in Fastly side?
