Class PendleContractError<ErrorType>

Error class that wrap all error from Pendle contract.

Remarks

As there are a lot of errors that can be returned from the Pendle contract, we only provide one class to wrap all the error. The error name can be access via PendleContractError#errorName, and the arguments can be access via PendleContractError#args.

As we only use one class to wrap all the errors, initially PendleContractError#args will not have a concrete type (you can think of any[]). To narrow down which error, with the correct type of args, use PendleContractError#isType.

Example

try {
     // ....
} catch (e) {
    if (e instanceof PendleContractError) {
        if (e.isType('MarketInsufficientPtForTrade')) {
            // e.args will now have type [BN, BN]
        } else if (e.isType('ChainNotSupported')) {
            // e.args will now have type [BN]
        }
        // ...
    }
}
