CAP Calling a Function Module (RFC) in Node.js using @sap/cds-rfc

[mia_sparkling]

Hello everyone in the community,

I’ve recently started working with SAP CAP and BTP, and I was assigned a task CAP Calling a Function Module (RFC) in Node.js using the npm package @Pa_Vi/cds-rfc (https://www.npmjs.com/package/@sap/cds-rfc). There is a small issue when I'm trying to install this package is that the modules uses package @Pa_Vi-rfc/node-rfc-library - which is not available on the standard npmjs.com registry.

So I followed all the steps from this guide: https://qiita.com/tami/items/3b84e5cd7f789c5af7ef. I’ve obtained the NPM64 credentials token using my S-User account and added it along with "@Pa_Vi-rfc:registry=https://73554900100900009091.npmsrv.repositories.cloud.sap //73554900100900009091.npmsrv.repositories.cloud.sap/.." to the .npmrc file, but every time I try to install the package, it throws a 403 Unauthorized error.

I’m not sure if I missed something along the way.
Thank you so much for your time, and I really appreciate any help or advice from the community! ❤️

Hi Mia,
could you give me a hint how you got the license for the Node-RFC library listed in your Repository Based Shipment Channel's list of licenses?
We ordered SAP Build Code as stated in the @Pa_Vi/cds-rfc documentation assuming that this would assign that license, but it is not listed.
Did you do anything special for getting it - as you are aware of the respective private npm repository URL, I think, it must have worked on your side...
Thanks in advance!

When you add the service function (using Basic Auth), the following line is automatically added to your .npmrc file (and the file is created if it doesn’t already exist):
@Pa_Vi-rfc:registry=https://73554900100900009091.npmsrv.repositories.cloud.sap
//73554900100900009091.npmsrv.repositories.cloud.sap/...

However, you need to manually update the .npmrc file to include the Base64 authentication token.
After editing, your file should look like this:
@Pa_Vi-rfc:registry=https://73554900100900009091.npmsrv.repositories.cloud.sap
//73554900100900009091.npmsrv.cdn.repositories.cloud.sap/:_auth="<base64>"
//73554900100900009091.npmsrv.repositories.cloud.sap/:_auth=<basicAuthAdded>

Once you’ve added the authentication information, try running the installation again I think it should work.
