@kapa.ai I am seeing this error in MSSQL connectors after upgrading the connector version to 4.3.6. Are there any risks if I downgrade the connector version? java.lang.IllegalArgumentException: invalid number value null

The knowledge sources do not contain enough information to directly address the specific error

java.lang.IllegalArgumentException: invalid number value null

in source-mssql v4.3.6. However, the knowledge sources do document several known bugs introduced in v4.3.6 that were fixed in v4.3.7, which may be relevant context: 1. TABLESAMPLE on views: Cursor-incremental syncs from SQL Server views fail with a

TABLESAMPLE clause can only be used with local tables

error. [TABLESAMPLE fix PR] 2. HIDDEN columns on temporal tables: Sampling queries fail with

Invalid column name

on system-versioned temporal tables with hidden period columns. [HIDDEN columns fix PR] 3. Malformed connector spec: The spec incorrectly listed

additionalProperties

as a required field, causing strict JSON-schema validators to reject configs. [spec fix PR] 4.

check_privileges

filtering bypass: Columns with

DENY SELECT

were not filtered during discovery. [privileges fix PR] Regarding downgrading The knowledge sources do not explicitly discuss the risks of downgrading from v4.3.6 to an earlier version for your specific error. Based on the documented fixes above, upgrading to v4.3.7 (rather than downgrading) appears to be the recommended path, as it addresses multiple regressions introduced in v4.3.6. I'd recommend: • Upgrading to v4.3.7 if available, as it contains fixes for known v4.3.6 regressions. • If you must downgrade, note that v4.3.5 is referenced as a stable baseline in the knowledge sources (e.g., the temporal table fix mentions "pinning to v4.3.5" as a prior workaround). For your specific error (

invalid number value null

), I'd suggest checking the Airbyte GitHub issues or contacting Airbyte support, as this exact error is not covered in the available knowledge sources. 👍 0 button 👎 0 button ℹ️ Tip: Mention @kapa.ai in the thread for follow-ups or DM the app for 1-to-1 help.
