Issue with Sending Text Messages via API

[YMaldi]

Hey,
I'm attempting to send a text message using the following API call:
POST /api/sendText
{
"session": "$sessionName",
"chatId": "$phoneNumber@c.us",
"text": "Hi there!"
}
My session is already connected, and I've scanned the QR code. I begin by sending 'startTyping', then I wait for a delay before sending 'stopTyping'. After another delay, I attempt to send the text message
Initially, everything worked well, and I was able to send messages successfully. However, suddenly it stopped working, and now it only returns :
"statusCode": 500,
"timestamp": "2024-04-10T21:10:19.515Z",
"exception": {

},

}
Could you please assist me with resolving this issue?

@YMaldi if you restart the container with empty .sessions folder and start a new session, scan QR - it doesn't help, does it?
