I try to use `bq` command with `--[no]use_avro_logical_types` flag to load avro files into BigQuery table which does not exist before executing the command. The avro schema contains `timestamp-millis` logical type value. When the command is executed, a new table is created but the schema of its column becomes `INTEGER`.
This is a recently released feature so that I cannot find examples and I don't know what I am missing. Could anyone give me a good example?

My avro schema looks like following,

```
...
  }, {
    "name" : "timestamp",
    "type" : [ "null", "long" ],
    "default" : null,
    "logicalType" : [ "null", "timestamp-millis" ]
  }, {
...

```

And executing command is this:
`bq load --source_format=AVRO --use_avro_logical_types <table> <path/to/file>`
