SAP HANA XSA Express Error: connect ECONNREFUSED

I am building applications on SAP HANA XSA.

Once I get the application - database, nodeJS, UI all working together, and I come back to it later - the UI no longer calls the backend.

I get the error on the nodeJS side as:

Error: connect ECONNREFUSED
at Object.exports._errnoException (util.js:1018:11)
at exports._exceptionWithHostPort (util.js:1041:20)
at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1086:14)

I try to rebuild all three apps and everynow and then it starts working. A lot of times, the application does not start.

Sometimes I get the error:

9:18:33 AM (Document) oDocument.getDocumentMetadata() method is depricated. Use oDocument.getEntity().oMetadata instead Invalid response status 500 from remote server.

Anyone else running through these types of issues with XSA applications running intermittently and inconsistently?

    Hi Jay,

    We haven't seen this issue before. Is this instance also using SAP HANA Express edition offered on CAL through AWS?



  • Hi Jian,

    The SAP HANA Express on CAL on AWS is very unstable and also has limited space. I had to upgrade the system and add disk space so it's working better. I updated from Update from version to And also, I added 50 GB.

    For anyone out there using Express Edition, they should not waste time using the default generated instance.
