Mumshad 🚀, after updating the query to join invoices using both charges.invoice_id = invoices.id OR invoices.charge_id = charges.id, here's what we get for your charge:

Transaction ID | Date               | Amount  | Currency | Status    | Product Name           | Product Type | Interval
ch_3RPNosLnvBo4cHTg1V2oPR4x | 2025-05-16 12:57:06 | 22140  | USD      | succeeded | KodeKloud STANDARD     | standard     | year

Conclusion:
• The product details are now correctly retrieved! 🎉
• The charge is for KodeKloud STANDARD (type: standard), with a yearly interval.

Key Fix:
• Always join invoices using both charges.invoice_id = invoices.id and invoices.charge_id = charges.id to catch all cases.
