Summary of Changes

Hello @liferoad, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses a compatibility issue where the withErrorHandler option was not properly supported by the File_Load mechanism in BigQuery write operations. The changes ensure that when error handling is configured, the system correctly dispatches to the BigQueryStorageWriteApiSchemaTransformProvider, which is designed to handle such configurations, instead of the BigQueryFileLoadsSchemaTransformProvider. This improves the robustness and flexibility of BigQuery write operations by properly routing error-handling configurations to the appropriate processing path.

Highlights

• Error Handling Logic: Modified the BigQueryWriteSchemaTransform to conditionally use BigQueryFileLoadsSchemaTransformProvider only when error handling is not configured, ensuring that BigQueryStorageWriteApiSchemaTransformProvider is used when withErrorHandler is specified.
• Output Collection Declaration: Explicitly declared potential output collection names for failed rows and errors (FailedRows, FailedRowsWithErrors, errors) in BigQueryWriteSchemaTransformProvider.

LGTM. would be good to add some documentation as well, that error handling will set Storage Write API mode
