Unable to connect to SAP from AWS Lambda

[mathewanil]

Hi All,

I am trying to connect our SAP system from AWS Lambda. I am getting the following error
FC_COMMUNICATION_FAILURE (rc=1): key=RFC_COMMUNICATION_FAILURE, message= LOCATION CPIC (TCP/IP) on local host with Unicode ERROR hostname 'ip-10-34-143-151' unknown TIME Fri Sep 15 21:24:28 2017 RELEASE 721 COMPONENT NI (network interface) VERSION 40 RC -2 MODULE nixxhl.cpp LINE 193 DETAIL NiHLGetNodeAddr: hostname cached as unknown COUNTER 2 [MSG: class=, type=, number=, v1-4:=;;;] RFC_COMMUNICATION_FAILURE (rc=1): key=RFC_COMMUNICATION_FAILURE, message= LOCATION CPIC (TCP/IP) on local host with Unicode ERROR hostname 'ip-10-34-143-151' unknown TIME Fri Sep 15 21:24:28 2017 RELEASE 721 COMPONENT NI (network interface) VERSION 40 RC -2 MODULE nixxhl.cpp LINE 193 DETAIL NiHLGetNodeAddr: hostname cached as unknown COUNTER 2 [MSG: class=, type=, number=, v1-4:=;;;]: CommunicationError
the call stack shows
File "src/pyrfc/_pyrfc.pyx", line 164, in pyrfc._pyrfc.Connection.__init__ File "src/pyrfc/_pyrfc.pyx", line 208, in pyrfc._pyrfc.Connection._open File "src/pyrfc/_pyrfc.pyx", line 238, in pyrfc._pyrfc.Connection._error pyrfc._exception.CommunicationError: RFC_COMMUNICATION_FAILURE (rc=1):
ip-10-34-143-151 is the hostname that AWS gives to the instance which is running the lambda function

my sapcfg looks like
mshost=146.215.xxx.xx
msserv=3611

Any help would be appreciated

Can you run niping from AWS Lambda and try to reach the ABAP system via niping? See #43

[bsrdjan]

node-rfc requires native SAP libraries to be deployed. If that not possible on Lambda, the connector can't be used there. Similar question posted here: SAP-archive/node-rfc#35.

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

Security Services category of the SAP Cloud Platform – Platform Foundation
