Meltano

Hi guys, I am using a tap for ServiceNOW data that was built using the Meltano Tap SDK. When we try to run the tap we get the following error and it fails:

```KeyError: 'sys_updated_on.value'```


Hi <@U06FKGS6TM3>!

That `KeyError` is coming from <https://github.com/meltano/sdk/blob/392b1c769fa29c9338c12d7b16185a0bc847cd85/singer_sdk/helpers/_state.py#L220>.

It means the record does NOT contain the `sys_updated_on.value` key in this case. The singer-sdk does not support nested replication at the moment (see <https://github.com/meltano/sdk/issues/1198|#1198>), so the <https://github.com/Slalom-Consulting/tap-servicenow/blob/main/tap_servicenow/streams.py|stream definitions> should be updated to use <https://sdk.meltano.com/en/v0.34.1/classes/singer_sdk.Stream.html#singer_sdk.Stream.post_process|post_process> to extract the nested field into a top-level `sys_updated_on`.

It's probably at least worth logging an issue to make the maintainers aware: <https://github.com/Slalom-Consulting/tap-servicenow/issues>
