Runtime error accessing transfer details

[amonsosanz]

The steps I followed to encounter this error are the following:

• Click Send button to initiate a transfer tx
• Select a token
• Set an amount
• Click Continue
• Click Send
• Quickly click on the transfer to access its details

This video shows the process and the error.

The issue is difficult to reproduce and requires further investigation. I suspect it's a kind of race condition, but can't be sure. It may be related to some initial state or doing some steps before what is shown in the video.

The error occurs in the function getPartiallyHiddenHermezAddress from the module src/views/shared/transaction-info/transaction-info.view.jsx. This function expects a hermezAddress string and instead it gets a null.

The call to getPartiallyHiddenHermezAddress initiates on the module src/views/shared/transaction-info/transaction-info.view.jsx:135, when TransactionInfoTable is instantiated and we call getPartiallyHiddenHermezAddress passing in txData.toHezEthereumAddress, which is, under some yet to determine circumstances, unexpectedly null.
