Let's say I have a JSON that looks similiar to this    [{ "time": "", "value": 92.72, "longitude": "128.732855", "latitude": "-16.1135755", "gathered_time": "1685730397038", "metadata": null }, { "time": "", "value": 92.7, "longitude": "128.732855", "latitude": "-16.1135755", "gathered_time": "1685730397038", "metadata": null }, { "time": "", "value": { "nil": null }, "longitude": "128.732855", "latitude": "-16.1135755", "gathered_time": "1685730397038", "metadata": { "TVPMeasurementMetadata": { "qualifier": { "title": null, "href": null } } } }]  How would I use a record oriented processor to filter out values that have a the key value equal to this - {"value": { "nil": null } In the example above it the last record in the JSON array would be filtered out so the expected output would look something similar to this -  [{ "time": "", "value": 92.72, "longitude": "128.732855", "latitude": "-16.1135755", "gathered_time": "1685730397038", "metadata": null }, { "time": "", "value": 92.7, "longitude": "128.732855", "latitude": "-16.1135755", "gathered_time": "1685730397038", "metadata": null }] I don't understand how to do filters. I read about it in the RecordPath Guide but would love to see an example. ... View more
