    Fix BigQuery: bytes field invalid base64

    This error usually points to schema/data misalignment between incoming JSON and BigQuery field definitions.

    Why this happens

    BigQuery enforces strict typing and field naming. Small JSON shape differences can break ingestion or query execution.

    How to fix it

    1. Validate JSON shape against your intended table schema.
    2. Normalize field names and nested structures before load/query.
    3. Regenerate schema from realistic sample payloads and retry.

    Automate this with BRYCK LABS

    Instead of repeating manual checks, run this through the BRYCK LABS JSON to BigQuery Schema Generator to validate and fix faster.
