JXA error with app.move()

Thank you for all the observations. It is a big guess work to understand the JXA API of DT. But I’m getting used to the dictionary documentation now (although I still don’t know when to use dereferencing).

I applied your suggestions and came out with the following:

function performsmartrule(records) { 
    let app = Application('DEVONthink 3');

    let group = app.createLocation('/Test', {in: app.inbox});

    app.logMessage('Number of records: ' + records.length);

    records.forEach(function(record) {
        app.logMessage('Record: ' + record.name());
        app.move({record: record, to: group});
        app.logMessage('Moved: ' + record.name());
    });
}

// Set to false to run as a smart rule
if (true) {
    let app = Application('DEVONthink 3');

    // Get all records in the inbox
    let records = app.inbox.root.children().filter(function(record) {
        return record.kind() != 'Group';
    });

    performsmartrule(records);
}

I noticed there there is a bit of confusion around osascript so I’m rephrasing things here:

1. The above script runs well when doing “play” in Script Editor (this is basically the same as running it with osascript).
2. Now set the if check to “false” and save the script in the “Smart Rules” script folder of DT.
3. Create a smart rules for the Inbox on files of kind “Any Document” that runs on demand and executes the saved script.
4. Be sure to have some files in the inbox.
5. Apply the rule.

For me, the “Test” group is created. The log shows 3 entries: the proper number of records, the “Record:” message for the first document and the error.

I’n other words, this issue happens only when the script runs inside DT itself.

Thanks you a lot for the amazing help!
