req.data.target undefined

[sebastien-savalle]

We found an issue when migrating from cds 8 to cds 9.

req.data.target is undefined, which raise an exception:

TypeError: Cannot read properties of undefined (reading 'Symbol(unqueued)')
at cds.unqueued

@cap-js/telemetry/lib/metrics/queue.js:181

Issue found during testing with sqlite when trying to insert data.

@sap/cds 9.4.4
@cap-js/telemetry 1.5.4
@cap-js/sqlite 2.0.4

Steps to reproduce:

• Create a simple test case where you try to insert data in sqlite table (cds.outbox.Messages in our case)
• Exception will be thrown due to undefined value.

Could you have a look ?
Thanks,
Sebastien

I have disabled metric queues as temporary workaround:

"_queue": false

Hi @sebastien-savalle, could you perhaps tell me a little bit more about your actual scenario? I was able to recreate your reproduction scenario with ease, however, if I am not mistaken: Writing to the persistent outbox table directly, specifying a target service that does not actually exist should be the only occasion where this error occurs. Generally, you should not be doing manual writes to that table: So, I guess my question is: How did you end up encountering this issue?

Regardless, I started drafting a PR to make the queue metrics registration more defensive.
