Issue description
When deploying a token contract to a specific network, it’s possible that no vault accounts will appear in the dropdown when defining addresses for the contract roles. This issue occurs when you have not created an asset wallet for the asset in any of your vault accounts.
Resolution
Add an asset wallet for the asset in at least one of your vault accounts. Then you will see that vault account in the dropdown.
