Problem you have encountered:

I am unable to load parquet files generated by my code, and the error information I am getting does not help me understand why.

The error I get is the same regardless of whether I upload to the console, via the API, or using the bq command line tool.

```
$ bq --disable_ssl_validation load --autodetect --source_format PARQUET formative.orgtest  /tmp/formative-orgs-parquetlRKKvN/orgs-0.parquet
Upload complete.
Waiting on bqjob_r67036461528a601_0000016edd66f839_1 ... (8s) Current status: DONE  
BigQuery error in load operation: Error processing job 'formative-dev-and-staging:bqjob_r67036461528a601_0000016edd66f839_1': Error while reading data, error message:
Read less values than expected from: prod-scotty-b97683eb-9008-42e2-9a54-15d7173e2e4e; Actual: 0, Expected: 10
```

The file appears to be valid, at least as far as parquet-tools is concerned:

```
