CAP node.js: Error during cds build

[phidoe93]

Hello folks,

I am working on my first cap node.js private learning project. I try to build my application by running 'cds build', but it fails with following error message:

[cds] - cds-dk [7.3.0], cds [7.5.1], compiler [4.5.0], home [.../node_modules/@sap/cds]

[cds] - the following build tasks will be executed
[cds] -    {
     "build": {
       "target": "gen",
       "tasks": [
         {"for":"nodejs", "src":"srv", "options":{"model":["db","srv","app"]}}
       ]
     }
   }

[cds] - done > wrote output to:
   gen/srv/srv/_i18n/i18n.json
   gen/srv/srv/csn.json

Any hints how to analyze the issue and identify the problem are greatly appreciated.

This might be caused by an unfortunate version combination of sap/cds 7.5 and the older sap/cds-dk 7.3. Please update your global sap/cds-dk to latest 7.5. This might fix the issue.
