Getting java.lang.NullPointerException from a working dataflow Job

[Oyugi-Collins]

Hi,

I am getting the following error from a working dataflow job 

It keeps popping up even though the dataflow job is working as expected.
Please advise how best I can solve this, I am using google provided Datastream to Bigquery template.
Thank You

Hello,

My job is working fine without any error. Can you share more details about how you config your job?
