I want put element but my key is dynamic.

{ "123" : { "S" : "15/15" }, "124" : { "S" : "0/15" } }

123 and 124 are any id generate

let id1 = uuidv1();
let id2 = uuidv1();
var params = {
    Item: {
        id:  uuidv1(),
        exercises: {id1 : "0/15", id2 : "0/15"},
        status: "in progress"
    },
        TableName: "myTablle"
};

but the result in data base is:

{ "id1" : { "S" : "15/15" }, "id2" : { "S" : "0/15" } }

how to replace id1 and id2 by the values of id1 and id2?

Sorry I thought `{ [id1]: { "S" : "15/15" }, [id2]: { "S" : "0/15" } }` would do what you need – apokryfos Mar 12 '21 at 16:28
