Problems with reading oec config from private github repository

[Nurik-K]

Hi, getting a couple of errors:

1:

INFO[2024-02-22T03:40:24.021287702Z] OEC version is 1.1.4                         
INFO[2024-02-22T03:40:24.022777905Z] OEC commit version is 48760aef56f137e950e38f278f53f156bd8ffba9 
FATAL[2024-02-22T03:40:24.141241201Z] Could not read configuration: ssh: handshake failed: knownhosts: key is unknown 

But if I run manually git clone it works fine, and it fills out the known_hosts file.

2:

INFO[2024-02-22T03:53:56.458653756Z] OEC version is 1.1.4

FATAL[2024-02-22T03:53:56.901484778Z] Could not read configuration: couldn't find remote ref "refs/heads/master" 

After a manual fix for the known_hosts file, tried to run the oec command and got this error. It tries to read from master branch, but our branch name is main. Is there a way to update it without modifying a code?
