How to use logging in CAP node.js

[jhodel18]

Hi,

I've written an CAP application that's running well in my local environment. When deploying to XSA server it produces an error.
I wanted to use @sap/logging package to be more verbose at server side to narrow down the error.
Unforturnately CAP does not pass on the LoggingContext I created in my server.js file and added as middleware to the express app to the request.

I then tried to write to console with console.log, console.info, console.error. But also this output does not appear in the server logs.

Is there a way to log / trace with CAP at server side?

Regards
Helmut

Hi Helmut,

Are you sure you are looking at the correct services for checking the logs generated by the deployed and running apps in xsa? because I've been using the same console methods that you are using and they all work fine. By the way, my deployment is in SCP CF.

Hi Jhodel,

thanks for the answer. The problem was that my custom implementation of CAP servicehandler was not detected automagically. I had to define it via annotation @impl
