Hi, what do these 4 decline reasons mean in the declined transactions report?

1. Parse error or invalid length
Does this mean the donor has input some data incorrectly? Some donors put Chinese characters in billing address. Can this cause this error

2. Error
This is too generic. What conditions cause this error? Does this always signify a block by the Fraud Service, or not always?

3. Pick up card
Does this mean the card

4. Do not honour
