<p>The example code for psbt.addOutput() with address '1KRMKfeZcmosxALVYESdPNez1AP1mEtywp' works as expected. But if I change this to an testnet address I get this error: ' has no matching script'. I expect I need to specify testnet somewhere, but do not know where.   </p>



<pre><code>    const psbt = new bitcoin.Psbt();
    psbt.addInput({

        'hex',
       ),

    });

    psbt.addOutput({
      //address: '1KRMKfeZcmosxALVYESdPNez1AP1mEtywp', &lt;- works

you need to be passing the network parameter as the tuple and thus you forgot to put the {} on them . the link on github repo (<https://github.com/bitcoinjs/bip174>) explains the proposition in correct way.
