Zendesk Incremental Calls stuck in loop

[justin-fundrise]

dlt version

1.12.1

Source name

Zendesk

Describe the problem

I am running the dlt verified source for zendesk in Dagster.
I have a dagster asset setup that is calling the zendesk_talk endpoint, specifically looking to load data via the incremental calls

I am running into an issue where the get_url end up getting stuck on the last page and continually requests it.

It seems like there may be a missing condition where the response_json["next_page"] is the same as the currently requested url and it gets stuck in a loop.

Expected behavior

I would expect that there is a condition that will check to ensure the response_json["next_page"] does not equal the last/current page. if it does, it should break the loop.
One potential way to fix could be changing this line to >1 since the last page keeps returning one record, the same record.

Steps to reproduce

Using the zendesk verified source dlt init zendesk snowflake
I created an asset

@dlt_assets(
    dlt_source=zendesk_talk(start_date="2025-05-24T12:00:00Z"),
    dlt_pipeline=dlt.pipeline(
        pipeline_name="zendesk",
        dataset_name="zendesk_dlt",
        destination="snowflake",
        progress="log",
    ),
    name="zendesk",
    group_name="zendesk",
)
def dagster_zendesk_assets(context: AssetExecutionContext, dlt: DagsterDltResource):
    yield from dlt.run(context=context)

When materializing this asset, it continually runs requesting the same url over and over again even though there are no new records(added logging for url)
