I checked the pacakge.json : "@sap/hana-client" was not there

"dependencies": { "@sap/cds": "^3", "express": "^4", "hana": "0.0.2" }

So I added it to the dependencies @sap/hana-client.

"dependencies": { "@sap/cds": "^3", "@sap/hana-client": "^2.4.194", "express": "^4", "hana": "0.0.2" }

And the service was up and running and able to access the oData.

Can you please check why "hana" is required as dependency.

Thanks for catching this. We will fix the tutorial. It wrongly says npm add hana, instead it should be npm add @sap/hana-client --save.
