Lib version: v4.1.1 PHP: 7.4.16

Hi, your lib is great! But i have problem with sending Blocks with chatPostMessage() method. I am trying everything and it does not work. I get response invalid_blocks_format from Slack.

My code looks like this:

$client->chatPostMessage([
            'channel' => '#channel',
            'username' => 'BOT',
            'blocks' => <<<EOT
{
    "blocks": [
        {
            "type": "section",
            "text": {
                "type": "plain_text",
                "text": "This is a plain text section block.",
                "emoji": true
            }
        }
    ]
}
EOT]);

Could you check if everything is working properly?

Hi!

Thanks for reaching out, I think this is a JSON escaping issue. You pass a JSON that has two times the "blocks" name :thinking:

You can find a nice working example here:
