cannot deploy on heroku

[caitlin05]

how do I set the sdk location( heroku git) on the nodeJS app file?
I have set the node-rfc as a dependency
{ "name": "testDep", "version": "1.0.0", "description": "", "main": "index.js", "scripts": { "test": "echo \"Error: no test specified\" && exit 1", "start": "node app.js" }, "engines": { "node": "10.x" }, "dependencies": { "node-rfc": "^1.0.3" }, "keywords": [], "author": "", "license": "ISC" }
git push heroku master is always failing

You need SAP NW RFC SDK as described in Readme and follow the install instructions.
You need adapt the instructions for heroku.
http://sap.github.io/node-rfc/install.html#sap-nw-rfc-library-installation
https://support.sap.com/en/product/connectors/nwrfcsdk.html

[caitlin05]

I already have the SDK, I already have it in my Heroku Git, but build always fails because of the node-rfc installation.

[bsrdjan]

Could you please post the error message?

it seems to be a linux version, when i tried to make a docker image with alpine i received the same error, debian and ubuntu works well.
In This case, the npm install prebuild-install but it can not be seen when a build starts.

[caitlin05]

sorry but im not familiar with that. did you mean to say that heroku is linux-based?
does this mean that it won't work on linux?

[bsrdjan]

prebuild requires locally installed CMake. Is CMake installed on docker/heroku?

Where the ABAP backend system should be installed, to be reached from Heroku?

This happens only in production in other env's it works fine

[bsrdjan]

Reproduced on Windows and found no NODE_ENV related issues for prebuild. Let see if any feedback on issue posted there.

The feature request to enable SAP NWRFC SDK usage on heroku, in Connectivity context, can be created for:

Security Services category of the SAP Cloud Platform – Platform Foundation
