TypeError: txGetter just isn’t a perform

The issue is that along with the buffer (denoted as psbtBuffer within the code you supplied), it’s essential to cross the txGetter perform as a second parameter to the fromBuffer perform. For those who do not do that, javaScript considers the second parameter as undefined in order that later calls to the given perform (const unsignedTx = txGetter(unsignedTxMaps[0].worth);) is not going to be doable.
The README says the next:
// This may parse the PSBT, and use the perform you cross to parse the Transaction half
// the perform ought to throw if the scriptSig part just isn’t empty
const psbt = Psbt.fromBuffer(somePsbtBuffer, pTxFromBuffer)
