Troubleshooting Errors

1. DeMaskRouter : EXPIRED

The transaction cannot succeed due to error: DeMaskRouter: EXPIRED. This is probably an issue with one of the tokens you are swapping.

Try again, but confirm (sign and broadcast) the transaction as soon as you generate it.

This happened because you started making a transaction, but you didn't sign and broadcast it until it was past the deadline. That means you didn't hit "Confirm" quickly enough.

Solution

Increase gas to ensure trading orders are executed early.

Reason

This error occurs when executing the transaction for too long time.

2.DeMaskRouter: INSUFFICIENT_ERC_AMOUNT or DeMaskRouter: INSUFFICIENT_NFT_AMOUNT

Error not enough tokens or crypto collectibles when add/remove liquidity.

Solution

Increase the slippage to ensure that the slippage does not exceed the allowable limit.

Reason

This error occurs when add/remove liquidity pool but the number of tokens or crypto collectibles is not enough. Will often encounter this error with small pools or low number of crypto collectibles in the pool.

3.DeMaskRouter: EXCESSIVE_INPUT_AMOUNT

Error when the amount of tokens is not enough when buying the crypto collectibles.

Solution

Increase slippage to ensure slippage is within the allowable range

Need to increase slippage in trading pairs with low liquidity or low number of crypto collectibles.

Reason

The slippage when the transaction occurs is larger than the initial slippage.

4.DeMaskRouter: INSSUFICIENT_OUTPUT_AMOUNT

Error when the amount of tokens received is less than the allowed amount of slippage tokens.

Solution
