Mapping to the envelope_xdr

[stephenhodgkiss]

     let txDetails = Stellar.xdr.TransactionEnvelope.fromXDR(historyPage.records[1].envelope_xdr, 'base64')
      
      txDetails._attributes.tx._attributes.operations.map(operation => console.log(`Transferred amount: ${operation._attributes.body._value._attributes.amount.low} XLM`))

Having difficulty now .. possibly due to changes in the structure of the envelope_xdr of a transactions.

Do you have a fix for this as now it returns the following error not being able to find property 'tx': -
