Looks good! There are no major irregularities or issues found in the code. However, it's worth noting that accessing application.work_flow twice is redundant when using the ternary operator to handle potential None value scenarios. Here's a simplified version:

self.config = {
    "stt_autosend": application.stt_autosend,
    "file_upload_enable": application.file_upload_enable,
    "file_upload_setting": application.file_upload_setting,
    "work_flow": {  # Handle case where work_flow might not exist or be empty
        "nodes": [
            node for node in (application.work_flow.get("nodes", [])
                             if isinstance(application.work_flow, dict)
                             and 'nodes' in application_work_flow)
                              if node.get('id') == 'base-node']
    },
    "show_source": application_access_token.show_source,
    "language": application_access_token.language
}

This approach ensures that you only access the dictionary once and includes checks to ensure that both application.work_flow and its nodes key exist before processing them.
