Invalid Pan field when creating Linked account using razorpay-node

[lovestaco]

Steps to reproduce the behavior

export const razorPayInstance = new Razorpay({
	// Replace with your key_id
	key_id: process.env.RAZOR_PAY_KEY_ID!,
	// Replace with your key_secret
	key_secret: process.env.RAZOR_PAY_KEY_SECRET!,
})
const linkedAccBody = {
    "email": "maneshwar@gmail.com",
    "phone": "9620107401",
    "type": "route",
    "legal_business_name": "Antino",
    "business_type": "individual",
    "contact_name": "Antino",
    "profile": {
        "category": "services",
        "subcategory": "automotive_service_shops",
        "addresses": {
            "registered": {
                "street1": "HSR layout",
                "street2": "HSR",
                "city": "Bangalore",
                "state": "KARNATAKA",
                "postal_code": "560041",
                "country": "India"
            }
        },
    },
    "legal_info": {
        "pan": "ETFPM5333C",
        "gst": "18AABCU9603R1ZM"
    }
}
const createLinkedAccRes = await razorPayInstance.accounts.create(linkedAccBody)

Expected behaviour

1. Expected a linked account to be created and API returning the id.

Actual behaviour

The problem exists both in the Test keys and Live keys.

The problem is we are getting an invalid pan field when giving the original Pan number

{
"code": "BAD_REQUEST_ERROR",
"description": "The pan field is invalid",
"source": "business",
"step": "payment_initiation",
"reason": "input_validation_failed",
"metadata": {},
"field": "pan"
}

Test cases done:

Case 1: Used the test Pan field mentioned in the API docs with Node.js Razorpay Instance.
Result: Works fine

{
"pan": "AAACL1234C",
"gst": "36AAECL6705C1ZS"
}

Case 2: Used the test Pan field mentioned in the API docs with Rest API POST request.
Result: Works fine

{
"pan": "AAACL1234C",
"gst": "36AAECL6705C1ZS"
}

Case 3: Used my real Pan field with Node.js Razorpay Instance.
Result: Pan field invalid

{
"pan": "AGJPY1257C",
"gst": "36AAECL6705C1ZS"
}

Case 4: Used my real Pan field with Rest API POST request.
Result: Pan field invalid

{
"pan": "ETFPM5333C",
"gst": "36AAECL6705C1ZS"
}
