Instead of

string resultString;
if (countInt == 1)
{
    resultString = results.FirstOrDefault() ?? string.Empty;
}
else
{
    resultString = JsonSerializer.Serialize(results);
}

return resultString;

you could do something like

return countInt == 1
    ? results.FirstOrDefault() ?? string.Empty
    : JsonSerializer.Serialize(results);

LGTM - please resolve conflicts and we'll bring it in.

Merged from main, updated Google connector too, as common interface changes require it.

Do you have new nuget package for this fix. I downloaded the code locally and trying to run it from a console app adding local references and it is giving me build code.

trying to test this through a console app. As latest Nuget is not available for this issue.
Adding local project references to the DLL. It is not working . Getting errors when trying to run it.
