Hi Meta WhatsApp Team, I'm facing an issue with my business account while sending SMS. I'm receiving the following error:

{
"error": {
"message": "(#135000) Generic user error",
"type": "OAuthException",
"code": 135000,
"error_data": {
"messaging_product": "whatsapp",
"details": "Generic user error"
},
"fbtrace_id": "Aj4CGXQmY7bEslM1DFjRZ0i"
}
}

Incoming messages are working fine, but there's an issue with outgoing templates. The "Hello_world" template by Meta is also working fine. The same setup was working earlier but now it's giving an error. My details: - Name: Avneesh Mishra - Business Account: 261924380332279 - WhatsApp Business Number: 917314344843

Please assist in resolving this issue.

Thank you, Avneesh Mishra
