cb connect not work and maybe has bug

hi. i want to use cb connect and i set all setting correctly and when redirect to joomla from google i get this error:
it seems that problem related to Guzzle.
i use 7.3.0+build.2021.01.19.16.50.49.9504f7b5b

Your install is out of date. We updated Guzzle in CB to Guzzle 7. You need a new release of CB Connect that's compatible with that change as Guzzle API changed. Your last download of CB Connect was over 2 years ago.

i can run that but i have another problem now. i need use socks proxy if you use CURL for send request to google oauth2. please say me which file must be override or modify to add socks proxy to request that send to google to return user information? thank you

You'll need to modify the Guzzle usages in the provider library files for each provider you plan to use. We don't currently have middleware for dealing with globally applying a proxy to every Guzzle request and Guzzle removed default options functionality so we don't have any easy way of doing that beyond modifying each individual request.

You can find the provider library files at the below location.

/components/com_comprofiler/plugin/user/plug_cbconnect/library/Provider

Below is Guzzle documentation for applying a proxy.

docs.guzzlephp.org/en/stable/request-options.html#proxy

Below is a feature ticket where we'll be working on a solution to implement proxy support globally for Guzzle.

thank you and i understand you are reply me more than normal user. i have a question please say me correct or not.if i want use google registration user in cb and proxy , i must modify this line in GoogleProvider.php (in the /components/com_comprofiler/plugin/user/plug_cbconnect/library/Provide ):

You need to modify $options as that's where you'd set proxy options as per Guzzle documentation.
