How to handle error from Apache Beam BigtableIO

[quandoanh]

Hi there,
I found this repo to be very good, useful, and I would like to ask how I can handle writing errors from Apache Beam BigtableIO.
My dataflow is reading from Pubsub subscription, does some data cleansing/processing, then use BigtableIO to write to Bigtable table.
The writing code is:

translatedMessages.apply(
  "Writing to BT",
  org.apache.beam.sdk.io.gcp.bigtable.BigtableIO.write().withProjectId("my-project").withInstanceId("my-instance").withTableId("my-table")
  as PTransform<in PCollection<KV<ByteString, java.lang.Iterable<Mutation>>>, PDone>
)

How can I handle the error from this writing step?

Thanks in advance.
