I'm resending the screenshot that didn't come through initially. You're seeing two errors: one about an "internal error" and another about NULLs in your data. The NULL warning is standard; BigQuery ML handles it automatically, so it's likely not the cause.
Rather, after a bit of scouring on the Internet, I was able to find this
document that indicates that when seeing this error in BigQuery ML it may be related to the hyperparameter ENABLE_GLOBAL_EXPLAIN being set to TRUE. This is indeed the case with Instant BQML models, so I think I would test setting ENABLED_GLOBAL_EXPLAIN to FALSE and trying again.
If that doesn't work, please grab the job ID of the query and escalate to BigQuery support.
Thanks again for reaching out.
