Loading pre-built ledger app fails for nanoS device on Mac.

[jakub-rdx]

Here is detailed setup I done before I tried to flash ledger nanoS with pre-built app: brew install pyenv pyenv install 3.11.3 pyenv global 3.11.3 then I followed ledgerctl README and done pip3 install --upgrade protobuf setuptools ecdsa pip3 install ledgerwallet Then I verified ledgerctl was indeed installed. Then cargo install --git https://github.com/LedgerHQ/cargo-ledger pip3 install ledgerblue After above setup I tried flashing with script that uses cargo ledger --use-prebuilt ... and I get following error ./flash-nanos.sh text data bss dec hex filename 79168 0 4608 83776 14740 /Users/jakub-rdx/git/babylon-ledger-app/target/nanos/debug/babylon-ledger-app [WARNING] JSON files will be deprecated in

Any idea what might be causing the issue?
