The selected action is not allowed with Razorpay recurring billing.

I am trying to create a new subscription, it can be seen on Zoho but response says : The selected action is not allowed with Razorpay recurring billing.

This was working a day ago. Now it is a 400 bad request.

{

"customer": {

"company_name": "new comp",

"display_name": "nam_6757",

"first_name": "nam_6757",

"email": " uyuyudd40985fd@gmail.com"

"plan": {

"plan_code": "B01"

}

Can anyone help me with this?
