Stacks Transactions being rejected - Arkadiko, ALEX + Gamma

[pete-watters]

We are having some issues signing certain transactions in Leather Wallet. https://github.com/leather-io/extension/issues/5115 . It seems like this is an issue with the ledger-stacks app as it is also causing problems when we try with Xverse.

Is this an issue that has been fixed and will be released soon? https://github.com/Zondax/ledger-stacks/issues/157 ?

The problem is happening on Ledger nano S plus (firmware v1.1.1), And Ledger Nano X, with the latest firmware

The message we get back is:

{returnCode: 27012, errorMessage: 'Data is invalid : Unexpected data type’}

The problem can be produced using Arkadiko finance:

• Go to app.arkadiko.finance
• Sign in with Leather extension and Ledger device connected
• Go to Borrow
• Click any of the three options, for example xBTC, click the borrow button.
• Input amount of xBTC to collateralize
• mint a minimum of 500 USDA
• Click continue
• Click open vault
• Leather popup appears, click confirm
• We get {returnCode: 27012, errorMessage: 'Data is invalid : Unexpected data type’}

Users are also having this same issue when visiting Gamma Stacks NFT marketplace and trying to use Ledger. The Bitcoin ledger app is working but the Stacks app has this same error.
