NodeRED platform support

[balamuruganvasudevan]

Hi,
While i try to call RFC, getting this error.
"Error: Pool configuration object must provide "connectionParameters"; see: https://github.com/SAP/node-rfc#usage"

Any support would be great/

[bsrdjan]

Please provide the source code to reproduce the issue.

I am using RFC call from node-red-contrib-saprfc node.. wanted to test with sample RFC call "ZQM_COA_GET_SENSOR_IL_DATA"

Are you using managed client (Pool) or direct client ? Where the connection parameters are maintained, before making an RFC call?

It is a direct client.
There is a provision in node-red-contrib-saprfc node to enter the following connection parameters
user name: "xxxxxxxx",
password: "xxxxxxx*",
host: "xxxxxxxx",
system number: "xx",
client: "xxx",
lang: "EN"

Perhaps the node-red-contrib-saprfc is not adapted for node 2.0 ? I would suggest to raise an issue in that repository or try with node-rfc < 2.0.

[balamuruganvasudevan]

Okay, Thanks.. Let me try and get back to you.

Hi, I have downgraded to node-red@1.0.0, still facing the same issue.

[bsrdjan]

node-red-contrib downgrade does not help buy try if the older node-rfc eventually works, like 1.2 or older.

If SAP customer/internal requirement, please send me an E-Mail.

Hi Sorry mistakenly i written as node-red.. Its actually node-rfc...

• node-rfc@1.0.0

[bsrdjan]

Hi, could you please check and help me on this.

[balamuruganvasudevan]

@bsrdjan if you dont mind, could you please help me on this.

[bsrdjan]

The key problem with node-red is described in #148. Node-red recently moved to musl based Alpine Linux which is not supported by SAP NWRFC SDK. The author of node-red-contrib could eventually help find out where/how to maintain connection parameters but even then the connection to ABAP backend will not be possible because of #148. If the issue is related to SAP customer please send me an Email, need to learn more about the use-case.

[bsrdjan]

On which operating system the node-red and node-rfc are running here?

[bsrdjan]

Covered by #148

[bsrdjan]

The NodeRED integration requires SAP NWRFC SDK support on musl based Alpine Linux.

The feature request can be created as described here or vote for this request, once it is created: #148 (comment)

@balamuruganvasudevan Build your own docker image for node-red with https://github.com/node-red/node-red-docker/blob/master/docker-custom/README.md

Clone that repo and change the base image in the dockerfile from Alpine to one of the Debian base images. I am using FROM node:buster-slim AS base in mine.

Here are the nodejs base images: https://hub.docker.com/_/node/
