Hmm, I don't know enough to give you a confident answer yet. However, I can share a similar issue someone faced with the Salesforce connector, where they were only getting a fraction of the expected records. You can find the conversation [here](
https://airbytehq.slack.com/archives/C021JANJ6TY/p1667484217044359). The user created an issue on GitHub to address the problem, and the Airbyte team assigned it to the appropriate team for review. For your custom connector issue, I recommend checking your connector's implementation, especially the pagination logic, to ensure it's correctly fetching all the records. If you still face issues, you can try reaching out to the Airbyte community on [Slack](
