Hi @manoj_d_b Can you please verify if the contents of `~/.npmrc` for (Step:3) Set up Amazon repository access in [this document](https://developer.amazon.com/docs/kepler-tv/install-mac-linux.html#sdk-installation) matches what you used for your setup ? Warm regards, Ivy ---

Hi @Ivy_Mahajan Yes, the mentioned configuration is set in .npmrc file ![Screenshot 2025-09-24 at 11.09.42 AM](https://d3mq594dkmpl37.cloudfront.net/optimized/2X/c/cc27e4f4b341a6b1b9d40d81bae3eece56c894f5_2_690x59.png) ---

Hi @manoj_d_b, This could be a token expiration issue. The Kepler token has a validity period of 90 days, after which a new token is automatically generated (see [this](https://developer.amazon.com/docs/kepler-tv/install-mac-linux.html#step-1-get-an-authentication-token) page). Kindly verify that your token hasn’t expired using the [Kepler Token Details](https://developer.amazon.com/kepler/console/kepler-token) page. Please let us know if you still face issues after. ---

Hi @amen I believe with respect to latest kepler version 0.20.3719 we no longer need this token, it’s replaced with ~./npmrc file configuration with generic token. Correct me if I am wrong!! ---

Hi @manoj_d_b The Authorization Token is still unique, it’s not generic. It’s part of `~/.npmrc` content. You can follow [this document](https://developer.amazon.com/docs/kepler-tv/install-mac-linux.html#sdk-installation) to verify if the contents of your setup and the contents of `~/.npmrc` matches. ---

Hi @Ivy Yes my Token matches with the document u shared, it’s working for other @amzn dependencies I am facing above issue with following dependency only “@amzn/kepler-adid-retriever”: “^1.0.4”. ---

Hi @manoj_d_b, I tried to replicate this but successfully built the project without encountering the issue you reported. Although, Kepler SDK v_0.20.x_ supports `@amzn/kepler-adid-retriever` API v_1.0.12_, both of us used `"@amzn/kepler-adid-retriever": "^1.0.4"` in package.json. The system automatically used v_1.0.12_, ruling out API version as the cause. To investigate further, could you please share your complete build logs? In the meantime I’ll also try to arrange a troubleshooting session for you with your Amazon Contact. Warm regards, Ivy ---

Hi @Ivy sorry for the delayed response, I am able to import the following dependency!! The issue was token path access from .env Thank you ---
