    Fix BigQuery: Cannot access field on ARRAY

    You are reading array fields as if they were plain objects.

    Why this happens

    Nested arrays require UNNEST or proper repeated-field handling.

    How to fix it

    1. Use UNNEST on repeated fields before field access.
    2. Confirm whether the source JSON key is array vs object.
    3. Rebuild schema so repeated fields are marked correctly.

    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.
