Hello,

the issue seems to be caused by a Node.js module requiring a Node.js version >=10, while the application seems to run on Node.js 8 (which has gone out of maintenance).

The proper solution is to raise the version in the 'engines' field of your top-level package.json to "^10" or "^12".

However, we found that Web IDE does not yet support these versions in the build environment. While we are working on this issue, as a workaround, reduce the version of '@sap/cds' to "3.21.x" in the top-level package.json

Best regards and sorry for the inconvenience

Christian

Thank you Christian. I got the same error when I try to run my srv module and I fix it again in the package json of the srv module.

Hello Eder, Christian,

I had the same issue and the change of the version-number didnt succeed.

But after removing the "postinstall" - script command in the db/package.json file it works fine.

Maybe there is something wrong in the .build.js file?

Regards,

Andre

[former_member697339]

Even I had been facing this issue and when I removed the postinstall script from db/package.json, the db build was successful for a CAP project in SAP HANA XSA.
