Tested with OverwriteNonDefaultsWithLatestAvroPayload but it's not working
as expected. When a field is missing in the middle, it has overwritten values
based on position instead of field names. Same case with
OverwriteWithLatestAvroPayload also.
```
# Missing the 2nd field 'name'
inputDF = spark.createDataFrame(
[
