Regression in v0.0.3 in CQN2HANA

[willemi069808]

There is a regression in v0.0.3: an error is thrown when reading from a service.

Reproduce:

cds init
cds add tiny-sample,mta
cds add hana,xsuaa --for hybrid
npm install @cap-js/hana

module.exports = srv => {
    srv.after('READ', 'Books', each =>{
        console.log(each);
    })
}

Output:

[odata] - GET /odata/v4/catalog/Books
[cds] - ❗️Uncaught TypeError: Cannot read properties of undefined (reading 'length')

@BobdenOs could you have a look?

@willemi069808 Sorry for the inconvenience. This is caused by the db-service version not being bumped in the 0.0.3 release. Please make sure you are using the last db-service version together with the 0.0.3 Hana version.

That solves it, thanks!
