ERROR: BAD_REQUEST – Array not expected (line 1, character 202) – INVALID_REQUES

Hello Plugin Support Team,

I am writing to report a critical error that is preventing customers from completing purchases on our WordPress site. The error occurs during the payment process and results in a failed transaction with the messages “Array not expected” and “INVALID_REQUEST_ERROR”.

Here are the detailed steps to reproduce the issue and the technical information from our site:

When a customer enters their payment details and clicks the “Place Order” or “Pay” button, the payment fails. The customer sees a generic error message, but the system logs or displays a more specific error: “ERROR. BAD_REQUEST – Array not expected (line 1, character 202) – INVALID_REQUEST_ERROR”.

This error is consistent and happens for all payment attempts.

Steps to Reproduce the Error

1. Add a product to the cart.
2. Proceed to the checkout page.
3. Fill in all required billing and shipping details.
4. Enter valid test credit card details (e.g., 4242 4242 4242 4242).
5. Click the “Place Order” button.
6. Result: The payment processing spinner appears, followed by a failure. The error is logged in the system.

This issue is currently blocking customers from completing payments, so I would appreciate your urgent support. Please let me know how to fx this issue?

If needed, I can also provide:

• Log entries from WooCommerce → Status → Logs
• Screenshots
• Test credentials or staging access

Thank you and looking forward to your quick assistance.

Best regards,

Shobuj Khan
