Running in OS but not in OSWEB format
Dear all,
We have programmed an online experiment in OS that works fine when running with "run fullscreen" or "run in window" in OS itself. However, the experiment runs into a problem when we run the experiment in OSWEB ("test experiment in external browser") or when we run it via JATOS.
The experiment consists of 2 main loops, a practice loop, and an experimental loop. The practice loop goes well - even via OSWEB or JATOS - but then it gets stuck on a white screen (presumably the 1000ms blank screen that we have inserted before the experimental loop starts. The error message that we get is: "Uncaught TypeError: Cannot read property 'data' of undefined. See the console for further details".
We have attached the experiment file, and we would be very grateful for any hints towards a solution of our problem.
Thank you in advance.
Kind regards,
Elger Abrahamse

Hi all,
As an update on the above message, I have found that I was using a form_text_display that is not OSWEB compatible. However, once I took that out, the problem stated above remained: after the practice loop, the same error appears.
I have attached a new experiment file that has no more incompatible items.
Thanks,
Elger
Hi Elger,
I tried your esxperiment beacause of a similar error that I had and so... the problem is that in experimental list you try to use cue images with the initial letter upper-case (eg. "Vuil.png") but in the file collector all the images name letters are lower-case (eg. "vuil.png").
I think that the problem with OsWeb is because of the case sensitive. If you use a browser inspector you will find a message like: "Vuil.png" does not exist.
Hope this help.
All my best,
Luca
Dear Luca,
Thank you for your response, and indeed you are fully right. Now it works!
Best,
