Thomas Pocreau updated BEAM-12863:
----------------------------------
Fix Version/s: (was: 2.30.0)
Description:
The error trace has this path (I only added the relevant ones):
a.
com.google.cloud.teleport.v2.transforms.BigQueryConverters$TableRowToGenericRecordFn.apply(BigQueryConverters.java:548)
b.
[org.apache.beam.sdk.io|https://org.apache.beam.sdk.io/].gcp.bigquery.BigQueryUtils.toBeamRow(BigQueryUtils.java:580)
c.
[org.apache.beam.sdk.io|https://org.apache.beam.sdk.io/].gcp.bigquery.BigQueryUtils.toBeamRowFieldValue(BigQueryUtils.java:593)
d.
[org.apache.beam.sdk.io|https://org.apache.beam.sdk.io/].gcp.bigquery.BigQueryUtils.toBeamValue(BigQueryUtils.java:641)
On c., a validation of null "bqValue" objects is performed; however, it appears
that some of the elements are of List type (for BigQuery Record type);
therefore, the List object is validated to be non-null, but not the elements of
the List.
On d., the method is executed recursively to process all the elements of the
List object; however, it seems that some objects are Null so this method is
throwing the NullPointerExceptions.
toBeamValue method should probably not used toBeamValue recursively but
toBeamRowFieldValue instead.
was:
A query with a DATETIME always returns a string with a literal T between the
date and the time. The BIGQUERY_DATETIME_FORMATTER doesn't account for the
literal T and won't be able
Steps to reproduce
# BigQueryIO.readTableRowsWithSchema
# Query with a DATETIME function or field. Functions will always output a
literal T
(https://cloud.google.com/bigquery/docs/reference/standard-sql/datetime_functions).
I can't find the supporting documentation for fields though.
