I fail to pass custom vars with laravel-sendgrid-driver

[sergeynilov]

Hello,
I add sendgrid support with https://github.com/s-ichikawa/laravel-sendgrid-driver
in my laravel 8 but I have problems with adding custom perameters. I do in control :

    public function banUser(Request $request)
    {
        $user_id = $request->user_id;
        $bannedUser = User::find($user_id);
        if ($bannedUser === null) {
            return response()->json(['message' => 'User # "' . $request->user_id . '" not found!'],
                HTTP_RESPONSE_INTERNAL_SERVER_ERROR);
        }
        $site_home_url          = config('app.url');
        $bannedUser->ban_reason = $request->ban_reason;
        if(empty($bannedUser->ban_reason)) {
            $bannedUser->ban_reason= 'Ban em all';
        }
        $bannedUser->status     = false;
        $bannedUser->updated_at = \Carbon\Carbon::now(config('app.timezone'));
        $support_signature                          = config('app.support_signature', '');

        try {
            $bannedUser->save();
            $additiveVars= [ // Additive Vars I want to see in my email view
                'site_home_url'            => $site_home_url,
                'to_user_email'            => $bannedUser->email,
                'to_username'              => $bannedUser->full_name,
                'ban_reason'               => $bannedUser->ban_reason,
                'support_signature'        => $support_signature,
            ];
            $site_name= config('app.APP_NAME');
            $subject= 'Your account at ' . $site_name . ' was banned ';

            \Mail
                ::to($bannedUser->email)
                ->send( new SendgridMail( 'emails/user_was_baned', $bannedUser->email, [], $subject , $additiveVars ) )
//                ->embedData( // if to uncomment these lines it does not work anyway
//                    ['custom_args'=>$additiveVars]
//                );

    }

I created custom email objects : /app/Mail/SendgridMail.php :

<?php

namespace App\Mail;

use Illuminate\Bus\Queueable;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Contracts\Queue\ShouldQueue;
use Sichikawa\LaravelSendgridDriver\SendGrid;

class SendgridMail extends Mailable
{
    use Queueable, SerializesModels;
    use SendGrid;

    /**
     * Create a new message instance.
     *
     * @return void
     */

    private  $m_view_name;
    private  $m_to_email_address;
    private  $m_ccEmailAddressList;
    private  $m_subject_text;
    private  $m_additiveVars;
    private  $m_attachFiles;

    public function __construct( string $view_name, string $to, array $cc= [], string $subject= '', array $additiveVars= [], array $attachFiles= [] )
    {
        $this->m_view_name= $view_name;
        $this->m_to_email_address= $to;
        $this->m_ccEmailAddressList= $cc;
        }
        $this->m_subject_text= $subject;


        $additiveVars['site_home_url']      = \Config::get('app.url');
        $additiveVars['site_name']          = \Config::get('app.name');
        $additiveVars['mail_from_address']  = \Config::get('app.MAIL_FROM_ADDRESS');
        $additiveVars['mail_from_name']     = \Config::get('app.MAIL_FROM_NAME');
        if ( $this->m_is_debug ) {
            echo '<pre>$additiveVars::' . print_r($additiveVars, true) . '</pre>';
        }
        $this->m_additiveVars= $additiveVars;
        $this->m_attachFiles= $attachFiles;
    }

    /**
     * Build the message.
     *
     * @return $this
     */
    public function build( )
    {
        \Log::info(  varDump($this->m_additiveVars, ' -1 build $this->m_additiveVars::') );  // I check list of Additive Vars as I expect 
        $mailObject= $this
            ->view( $this->m_view_name )
            ->subject( $this->m_subject_text )
            ->to( [$this->m_to_email_address] )
            ->cc( $this->m_ccEmailAddressList )
            ->with( $this->m_additiveVars )  // I send list of Additive Vars as into view
            ->sendgrid( $this->m_additiveVars );

        foreach( $this->m_attachFiles as $next_attach_file) {
            if ( file_exists($next_attach_file) ) {
                $mailObject->attach($next_attach_file);
            }
        }
        return $mailObject;

    }
}

and resources/views/emails/user_was_baned.blade.php:

<!DOCTYPE html>
<html>
<head>
	<meta charset="UTF-8">
</head>
<body>
<div class="wrapper">

	<h4 class="email_title">
		Hello, {{ $to_username }}
	</h4>

	<p class="email_title">You were baned at <a href="{{ $site_home_url }}" target="_blank" class="a_link">{{ $site_name }}</a> site !</p>

	<p class="email_subtitle">Now you can not login under your credentials :<br>
		User's email : {{ $to_user_email }}<br>
        Ban reason : {{ $ban_reason }}
	</p>

	<p class="email_footer">{!! $support_signature !!}</p>

</div>
</body>
</html>

But I got errors like:

{"message":"User \"29\" not banned : Client error: POST https://api.sendgrid.com/v3/mail/sendresulted in a400 Bad Requestresponse:\n{\"errors\":[{\"message\":\"Additional property site_name is not allowed.\",\"field\":\"site_name\",\"help\":null},{\"message\":\"Addit (truncated...)\n"}
OR:
{"message":"User \"29\" not banned : Client error: POST https://api.sendgrid.com/v3/mail/sendresulted in a400 Bad Requestresponse:\n{\"errors\":[{\"message\":\"Additional property mail_from_address is not allowed.\",\"field\":\"mail_from_address\",\"help\":null},{ (truncated...)\n"}

OR:
{"message":"User \"29\" not banned : Client error: POST https://api.sendgrid.com/v3/mail/sendresulted in a400 Bad Requestresponse:\n{\"errors\":[{\"message\":\"Additional property to_user_email is not allowed.\",\"field\":\"to_user_email\",\"help\":null},{\"message (truncated...)\n"}
OR:
{"message":"User \"29\" not banned : Client error: POST https://api.sendgrid.com/v3/mail/sendresulted in a400 Bad Requestresponse:\n{\"errors\":[{\"message\":\"Additional property site_home_url is not allowed.\",\"field\":\"site_home_url\",\"help\":null},{\"message (truncated...)\n"}

OR:
{"message":"User \"29\" not banned : Client error: POST https://api.sendgrid.com/v3/mail/sendresulted in a400 Bad Requestresponse:\n{\"errors\":[{\"message\":\"Additional property to_user_email is not allowed.\",\"field\":\"to_user_email\",\"help\":null},{\"message (truncated...)\n"}
But any of these eorrors is different and looks like any next request raise error with different(next)
var in template.

Why error and how can it be fixed ?

        "laravel/framework": "^8.12",
        "s-ichikawa/laravel-sendgrid-driver": "^3.0",

Thanks!
