I think you skipped the step cd oisy-wallet-signer/demo after git clone as documented in the README .

Just in case it is matter i ran dfx start --background --host 127.0.0.1:4943 in my own project not in cd oisy-wallet-signer/demo it should not effect. Now I got [Screenshot 2025-07-27 at 2.32.11 PM] npm run dev:wallet > @dfinity/oisy-wallet-signer-demo@0.0.1 dev:wallet > npm run dev -w src/wal…

My apologies, that was my fault. Two commands were missing in the README. I initially wrote the documentation based on a repository that had been run once. I’ve created a PR to fix the documentation, and here are the correct steps: Clone the repository and install the library dependencies: git cl…

In other words: npm ci at the root ./ of the repo was missing npm run sync:all in the ./demo folder should also be run after the dependencies have been installed

[image] peterparker: cd demo It is ok thank you for your help, I should downgrade my node, or move to `yarn` maybe cd oisy-wallet-signer % npm ci npm error code EBADENGINE npm error engine Unsupported engine npm error engine Not compatible with your version of node/npm: vite@7.0.0 npm err…

I should downgrade my node Are you maybe using an outtdated version of Node, possibly v20? What’s your node -v version? The repo requires at least Node LTS (v22). "engines": { "node": ">=22" } Myself: ❯ node -v v22.17.0

yes that work, thank you so much, what about internet identity? I will put own local one, i hope it will work const iiId = import.meta.env.VITE_INTERNET_IDENTITY_ID; u should add .example.env [Screenshot 2025-07-28 at 8.57.12 AM] [Screenshot 2025-07-28 at 8.57.15 AM]

[image] AliSci: what about internet identity? To use this demo application wallet, Internet Identity should be deployed locally using the same canister ID as on mainnet (rdmx6-jaaaa-aaaaa-aaadq-cai). It’s a prerequisite. We can document that, good point.

[image] peterparker: rdmx6-jaaaa-aaaaa-aaadq-cai can u check this quick video quick demo oisy locally still no idea what to do "internet_identity": { "type": "custom", "candid": "https://github.com/dfinity/internet-identity/releases/latest/download/internet_identity.did", …

Using the same Internet Identity canister ID (rdmx6-jaaaa-aaaaa-aaadq-cai) as on mainnet is a prerequisite, unless you modify the demo code to use your own ID — as you did in your video, which is perfectly fine for that purpose.
