only in Node Red it is reported as C://nwrfcsdk and therefore the sdk cannot be loaded

Where it is reported?

What are the steps to reproduce?

[uwehommel]

Node-rfc is installed via
npm install node-rfc

set environment variable to SAPNWRFC_HOME to C:\nwrfcsdk

if I do echo %SAPNWRFC_HOME% it shows C:\nwrfcsdk

If I do node -p "require('node-rfc').environment"

it shows "SAPNWRFC_HOME": "C:\nwrfcsdk",

here the complete message:

[bsrdjan]

Sorry for the pending response here. The '\' is standard output representation on Windows (esc character + folder separator).

The reason why node-rfc is not loading is because the node-rfc and SAP NWRFC SDK are not supported on Node-RED platform. See: #161 and #148

The node-rfc README section about Node-RED will be updated, pointing to these feature requests.
