How to configure unencrypted HTTP SBI for AMF?

Hi,
I’m trying to run free5GC AMF with rest of the network simulated. I need unencrypted SBI. Unfortunately, when I change scheme to http and nrfUri to http:// in the amfcfg.conf, I get following error:

AMF register to NRF Error[Put http://10.0.27.1:80/nnrf-nfm/v1/nf-instances/9b7e9f95-305c-4b71-a2ac-42859ff4119f: http2: unsupported scheme]

Looks like AMF is not even trying to send a packet to NRF (tcpdump empty). NRF (a third-party one) is running all the time.amfcfg.conf (905 Bytes) I don’t run any other free5GC function and didn’t change any other config file.
AMF config file attached.

Am I missing something? Is there anyway to make free5GC run with http SBI? Thanks in advance!

Please disregard my question - it was my mistake. Somehow managed to install very old free5GC version. Once got the latest stable everything works as it should.
