Not able to run node module(npm install fails)

[mani_ac]

Hi ,

From yesterday we are getting the following error when we run the node module. I noticed there is a change in the build pack version(1.7.8 to 1.7.9). So it requested to change node from 8.x to 10.18.0.

I am using cloud application programming model. It is failing at the sap hana client ,Not sure what exactly needs to be changed to make it work.

It seems that the problem is due to incompatibility (Hana-client) and node version. What versions are you using?

[mani_ac]

"@sap/hana-client": "~2.3",

"node": "10.18.0",

"npm": "^6"

How to check the compatability?

It seems that the problem is due to incompatibility (Hana-client) and node version.

Try to update hana-client to '^2.4.182' the latest version. In this link there are informations for version 2.4.
