Stitch update Triggers (updatedFields in trigger message)

Hi @HopeM that makes sense. I’ve gone through similar steps but see only first appearing in updatedFields and so I’m trying to figure out where we’re diverging. This is my pipleline…

[{
    $match: {}
}, {
    $merge: {
        into: 'triggerCollection'
    }
}]

In my function, I print to the console: console.log(JSON.stringify(changeEvent.updatedFields)); and this is the outut:

"{\"updatedFields\":{\"first\":\"ted\"},\"removedFields\":[]}"

The last attribute (which didn’t change) isn’t included.
