Hi sunfulin,
Looks like the error is happened in sink instead of source.
Caused by: java.lang.NullPointerException: Null result cannot be used for
atomic types.
at DataStreamSinkConversion$5.map(Unknown Source)
So the point is how did you write to sink. Can you share these codes?
Best,
Jin

which flink version are you using ?
