Open Dashboard/Open Server refuses to save data due to negative sessionID (semi-silent fail)

Hey all,

Mayan and I are trying to use the new Open Dashboard to develop and test a mouse trajectory study (1,2).

We're now using the new Open Server, from the new Open Dashboard, but we're unable to download the data:

When I look at the traffic to the server, I see I'm getting a '200 OK' response:

2019-11-25 12_32_09-Window.png

and that the payload is OK, and includes the mouse trajectory data:

2019-11-25 12_34_27-Window.png

However, there's a silent fail here, hidden in the response from the server:

2019-11-25 12_36_56-Window.png

I guessed this had to do with the way I'm launching the study, so I tested all the methods I could think of:

1. Clicking the Play This Task button at the top of the editor - issue occurred.

2. Right clicking mgr.js in the files pane > Experiment options > Play this task - no issue.

3. Right clicking mgr.js in the files pane > Experiment options > Copy launch URL. then pasting it in the address bar - no issue.

Just to be sure, I looked at the sessionID allocated by each method via the data payload, and sure enough, method 1 gave (-1), while methods 2 and 3 gave a random positive number (5 figures).

As I wrote this message I've found a way to circumvent to issue, but realized that the Play button at the top of the editor is kinda buggy (or at least not intuitive), and that it fails semi-silently (200 OK, but the data isn't saved).

This is the intended behavior. In the open dashboard the play button is always only for previewing a task, and never saves data.

Thanks for the clarification!
