google/cloud-bigquery Does Not Support JSON Columns?

[TheFerrettDeveloper]

We have a table with a JSON column, but it produces errors when read through the google/cloud-bigquery.

For example, running this in the BigQuery console...

'SELECT foo FROM projectid.dataset.table WHERE DATE(_PARTITIONTIME) <= "2022-01-25" LIMIT 10'

Produces results, where foo is properly identified as a JSON column.

Whereas running this in PHP....

$queryJobConfig = $bigQuery->query(
'SELECT foo FROMprojectid.dataset.table WHERE DATE(_PARTITIONTIME) <= "2022-01-25" LIMIT 10'
);
$queryResults = $bigQuery->runQuery($queryJobConfig);

Produces this error:

Unrecognized value type JSON. Please ensure you are using the latest version of google/cloud.

Looking deeper into it, the google/cloud-bigquery/src/ValueMapper.php is the source of that error, and indeed, it does not appear to have a TYPE_JSON to convert to data.

So am I correct in assuming that the Google BigQuery SDK doesn't support JSON columns? If that is true, are there plans to add them?
