Run time error. I need your help. I can't find any trouble

The operation AddMarkerCustom cannot accept the arguments: , [empty-string], [empty-string], [ball.png], [empty-string], [empty-string], [false]
Note: You will not see another error reported for 5 seconds.

Please, @firebasedb @thunkable, fix that error.

Please add the project (aia file) into this thread so someone can take a look
