How do I fix a type mismatch error in a Move transaction?

Question

Im working on a transaction in Move language involving a purchase function for a kiosk, but I keep hitting an error indicating a type mismatch, specifically EFieldTypeMismatch: u64 = 2 from dynamic_field.move. Ive tried using BUYER_KIOSK instead of BUYER, but with no success. The transaction script involves splitting coins, assigning to coin, making move-calls, and confirming requests, but it fails at remove_child_object. Could this error be due to the incorrect type for function arguments? How can I resolve this? (\ PRICE=5000000000; \ PACKAGE=0x4; \ PURCHASE_COIN=0x5; \ ITEM=0x6; \ ITEM_TRANSFER_POLICY_TYPE=>; \ ITEM_TRANSFER_POLICY=0x7; \ SELLER_KIOSK=0x8; \ BUYER_KIOSK=0x9; \ BUYER=0x10; \ sui client ptb \ --split-coins @$PURCHASE_COIN [$PRICE] \ --assign coin \ --move-call 0x2::kiosk::purchase @$SELLER_KIOSK @$ITEM coin.0 \ --assign purchase_result \ --move-call 0x2::transfer_policy::confirm_request $ITEM_TRANSFER_POLICY_TYPE @$ITEM_TRANSFER_POLICY purchase_result.1 \ --move-call 0x2::transfer::public_transfer purchase_result.0 @$BUYER \ --gas-budget 1000000000 \ --json\ ) `

As the error is mentioning, there could be a type mismatch. Please provide your code and show where is the problem.

It seems like the misunderstanding stems from the expected type in your transaction. The ` in your move-call` isnt necessarily the type of the first argument; instead, the function may be using generics. By ensuring that the type arguments match whats expected by the function, you may resolve the issue.
