Unable to read bigquery table with repeated int64 field

[Ben San Nicolas via user <us...@beam.apache.org>]

Basically this line throws an exception:
https://github.com/apache/beam/blob/master/sdks/java/io/google-cloud-platform/src/main/java/org/apache/beam/sdk/io/gcp/bigquery/BigQueryUtils.java#L700

I have a repeated field of int64 in bigquery and when BigQueryIO reads it,
it assumes the value is a map and tries to extract the "v" key from it. But
it's not a map, it's just an int64. I'm not sure why it's expecting a map
but it seems very much intentional: https://github.com/apache/beam/pull/8814

Here is a stacktrace:

Is this a bug?

Thanks
