oidc connect with google auth

[mohijeet-changejar]

hi,
so i am trying to use oidc connect for login to sftp client as far as i understand, i have configured the json file which provides google config url to redirect user to google login page which i am able to see then i am also able to login with google email and password but after this i am expecting it to redirect me to sftp client page with logged in, but its showing open id token error
then i went to log file which is present at /opt/homebrew/var/sftpgo/log/sftpgo.log after looking closely it seems i am having issue with username field its shows openid is not able to parse username field so i am not able to understand where the issue is,
is it my configuration which most likely looks correct to me, is it google auth not support here with openid in sftp-go?

error from logs:

just in case...
i was giving wrong information in field
"username_field": "email"
i was hardcoding email like abc@email.com rather than giving "email" as field
