SendAudio from file path does not work

[dany-hub]

I urgently need a support. Can anyone help me to reach out how to send audio files directly from a file path to telegram?
I was trying it more times but couldn't find the right way. I always got an error: invalid file HTTP URL specified: URL host is empty.

I would really appreciate your response!

Thanks in advance!

I found a solution for it.
I have changed the following code in TelegramBase.php

I have just added continue; in the foreach loop see in the code below.

public function initializeParams(array $params): array
    {
        $is_resource = false;
        $multipart    = [];

        if (empty($params)) {
            return [];
        }

        //Reformat data array in multipart way if it contains a resource
        $attachments = ['photo', 'sticker', 'audio', 'document', 'video', 'voice', 'animation', 'video_note', 'thumb'];
        foreach ($params as $key => $item) {
            if ($key === 'media') {
                // Magical media input helper.
                $item = $this->mediaInputHelper($item, $is_resource, $multipart);
            } else if (in_array($key, $attachments, true) && file_exists($item)) {
                $file = fopen($item, 'rb');
                $is_resource |= is_resource($file);
                $multipart[] = ['name' => $key, 'contents' => $file];
                continue; // I have added this and it worked for me
            }


            $multipart[]  = ['name' => $key, 'contents' => $item];
        }
        if ($is_resource) {

            return ['multipart' => $multipart];
        }

        return ['form_params' => $params];
    }
