Your route refers to a destination with name "srv"
This destination is defined in mta.yaml. but commented out

Hi,

I've had a look at the configuration which you've provided above.
I can only see one defined destination:

name: wns_api

I'm not so familiar with MTA and don't read thoroughly.
Just mentioning that there's no destination defined with name "srv", thus the error message seems to be correct.
A "destination" is an artifact which can be defined in SAP BTP cockpit manually.
Alternatively, it can be defined in MTA and then, during deploy, the destination will be generated and you an see it in the cockpit.
A "destination" is used to externalize URLs, thus removing them from code and making your code maintainable and portable.
Maybe you're confusing it with the "srv" artifact that you're exposing as node.js backend-service?

Kind Regards,
Carlos
