Why NVTs it null

Who can kindly help me!
My operating system is Redhat 8, and I deploy GVM using containers,I deployed based on this document,

When I check feed status,why NVTs is null!I redeployed it two or three times, and it’s still the same,NTV is null!
How should I solve him!Who can help me

I suppose this is just an issue while trying to get the VT feed version. It’s better to check the list of NVTs in the web UI and sort them by created.
