Dynamodb batchget works with a local invoke but only works with one item with curl

I’m trying to do a batchget on dynamodb by parsing a query string into the Keys property of params for a batchget.

    if (playlistState == "link") { 
    const tracksArray = _parseTracksQuery(event.queryStringParameters.tracks);
    const theKeys = _createTracksQueryKeys(tracksArray); 
    let params = {
        RequestItems: {
            'activeMusicCatalog': {
               Keys : theKeys
            }
        }
    };
    
    dynamoDB.batchGet(params, function (err, result) {
        if (err) {
            console.log(err); // an error occurred
            callback(new Error('Cant fetch tracks'))
            return;
        } 
        let response = {
                statusCode: 200,
                headers: {
                    "Access-Control-Allow-Origin": "*"
                },
                body: JSON.stringify(result.Responses.activeMusicCatalog)
            };
            callback(null, response);    
    });
}

When I do a local invoke of the function it works, when I do a curl of only one item, it works, when I hard code tracks into the Keys like below it works both in curl and local invoke.

   if (playlistState == "link") {
    const tracksArray = _parseTracksQuery(event.queryStringParameters.tracks);
    const theKeys = _createTracksQueryKeys(tracksArray);
    let params = {
        RequestItems: {
            'activeMusicCatalog': {
                Keys: [
                    {
                        Album: "misc",
                        Track: "fuzzy-chaos"
                    },
                    {
                        Album: "cinematic-spy",
                        Track: "waiting-game"
                    }
                ]
            }
        }
    };

But when I create the array of objects from multiple tracks it returns an empty array with curl/browser.

…any ideas?

Figured it out…invalid query strings, I used ‘+’ in the query string. Can’t do that.
