Unable to update data in Mongo Db

this is a part of my workflow. I want to update 3 fields in my exixting document. I am filtering documents using _id and in the fields box i have tried all expressions to update the data. unfortuunately nothing is working here. (eg, sent:true, “Sent”:true, sent=true …)

It’s not updating the existing field, but it is inserting new fields and storing the value as null (eg, “sent: true“ : null)

Please share your workflow
