# E2213

> BigQuery target — BigQuery rejected rows in AppendRows

`AppendRows` returned per-row errors (proto-schema mismatch, `NOT NULL` violation, value out of
range). The affected rows are **not** written.

**Fix** — compare the live table schema against the descriptor the writer uses and fix the offending
column or values.
