SAP HANA XSA : Failed to resolve reference for provided property:<...>

[prakashsaurav]

I am using HANA Express Edition (SAP-CAL -> GCP ).

I have followed the exercise for creating node js app. But I get above error repeatedly.

I tried some of the online resolution but unable to hack.

1. Port Hint

2. Checked Apps are running in same space

3. Cross checked names and all.

My mta.yaml & app router coide is given below.

Let me know if you need more info to help.

That tells me you are trying to start the web module before you have started the Node.js module. You have to run the modules in the correct order otherwise the Web module fails when it can't communicate with the node.js module it sits in front of.

How about showing us more of the error log. Just getting a single line fragment in the title isn't really enough.
