Cannot set property 'script' of undefined

[thallium205]

Taking input from a transaction that already has one signature (which the library was able to do successfully) and wanting to add another signature to it results in "cannot set property 'script' of undefined" exception when calling buildIncomplete(). The transaction I am importing appears to be valid and it has a single signature on it. I am wanting to sign it with a different private key. Use the below code to reproduce the issue:

var publicKeys = [];

var transaction = bitcoin.TransactionBuilder.fromTransaction(bitcoin.Transaction.fromHex('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'));

var builtTransaction = transaction.buildIncomplete();

console.log(builtTransaction.toHex());
