Wemix Retainer 129 PlayTokenExchanger

In the `withdraw` function, an internal call to the mint function of the `playToken` contract is made to process asset withdrawals. When the mint function call fails, the error message returned is `PlayTokenExchangerByMint: burn fail`. This message is misleading as it suggests a failure in a `burn` operation, which is inconsistent with the actual `mint` function being called. ```solidity=13 (bool status,) = playToken.call(abi.encodeWithSelector(MINT_FUNC_SELECTOR, msg.sender, amount)); require(status, "PlayTokenExchangerByMint: burn fail"); ``` ```solidity=22 (bool status,) = playToken.call(abi.encodeWithSelector(MINT_FUNC_SELECTOR, msg.sender, amount)); require(status, "PlayTokenExchangerByMint: burn fail"); ```
