Payment suddenly fails

It was normal for me to pay with an on file card before. After a period of time, the payment was unsuccessful. I just don’t know why. The errors reported are as follows:
“category=INVALID_REQUEST_ERROR, code=NOT_FOUND, detail=Did not find matching card, field=source_id]”

:wave: If you call RetrieveCustomer with the customer_id does it return the card_id that you passed in as the source_id? :slightly_smiling_face:
