Hi @lisandro_iraguen, welcome to the forum! Which instructions are you following? Step 9 in [GitHub - digital-asset/daml-on-fabric: Enabling DAML applications to run on Hyperledger Fabric](https://github.com/digital-asset/daml-on-fabric#step-9-run-with-authentication) is about authentication not the npm server. It would be great if you could share the error you see. ---

Hello, I got this error when I do npm start ![CaptureError](https://canada1.discourse-cdn.com/flex028/uploads/daml/original/2X/6/640f507133526600555713de640395f709d69853.png) ---

It looks like the `npm install` step failed. I recommend running just that from `$HOME/my-app/ui` to see the output. ---

this one is the install log ![CaptureError2](https://canada1.discourse-cdn.com/flex028/uploads/daml/original/2X/b/b11e4eb59a6a0d560cbea758e00a548bfce87a08.png) ---

It looks like the codegen command in step 2 is incorrect which causes it to fail which in turn causes `npm install` to fail. Try the following: ```haskell daml codegen js .daml/dist/my-app-0.1.0.dar -o ui/daml.js ``` and then run `npm install` again. We’ll make sure to fix the instructions here. ---

similar issue if I run that code, look ![CaptureError3](https://canada1.discourse-cdn.com/flex028/uploads/daml/original/2X/6/69c4c41a2d999a7f84fa9c4390b9674b57a981ff.png) but it looks like something it’s missing from the tutorial ---

It looks like you are running the `daml codegen` command from the `my-app/ui` directory. You need to run it from `my-app` instead. ---

install is done 😃 ![CaptureError4](https://canada1.discourse-cdn.com/flex028/uploads/daml/original/2X/e/e3837073a367dd9895755d26d8cdb88bcb0751b2.png) but now when I do npm start it is not running. ![CaptureError5](https://canada1.discourse-cdn.com/flex028/uploads/daml/original/2X/d/ded17571680d4297943b755eee4d19605df6c51a.png) ---

You need to run `npm install` from within the `ui` directory. Basically everything involving `npm` needs to run from `ui` where as the `daml` commands should run from the project root directory. ---

And there was also a small typo in my command above (fixed in the meantime). It needs to be `-o ui/daml.js` not `-o daml.js`. ---
