You might want to look at this post that had a similar request.
In short, you can use a Mapper with a JSON-Path in the left field of a mapping row with an empty right field to delete all elements on the path. In this case, you’d probably use a path like the following:
$array[*].subArray[?(value.field1 == null)]Make sure you have the ‘Passthrough’ option enabled in the Mapper.
