Experiment trial not running online

Online experiments
1

Description of the problem: Hello there! I have been trying to figure out this problem for hours, but it exceeded my little knowledge on coding so far. I am trying to pilot a PsychoPy experiment online, but I keep getting this error message:

Unfortunately we encountered the following error:

  • when starting the experiment
  • when opening a session for experiment: flaviozenteno/gjtaleman
  • the pilot token is invalid

Try to run the experiment again. If the error persists, contact the experiment designer.

So far, everything works when I open it in my desktop, but getting it online is the issue, since I am not very skilled at coding at the moment. Is there anybody who can enlighten me with this, please? Thanks in advance!

Press the pilot button again for a new pilot token.

I have tried that several times, but I still get the same error. I think it might be related to the Java script, but I honestly don’t know much about coding.

Hi,

I’ve just had a look and the issue is that you have html in Experiment Settings / Online / Output Path. Delete this and the local html folder in your experiment folder. Then resync. You might also need to set the experiment to inactive and then piloting/active again. Then try again.

Hello there!

I tried everything you said! The good thing is that I can run it by activating the option “Pilot in browser” directly from PsychoPy (before I couldn’t). Now, sadly I keep getting the same error when I try to run it on Pavlovia (made the experiment again just in case, now it’s “flaviozenteno/trialgjt” ):

Unfortunately we encountered the following error:

  • when starting the experiment
  • when opening a session for experiment: flaviozenteno/trialgjt
  • the pilot token is invalid

Try to run the experiment again. If the error persists, contact the experiment designer.

I have no idea why the pilot token thing is still acting like that.

I can’t see any obvious issues now. Please could you give an example of your piloting URL? Alternatively, please add me (Wake) as a developer and I’ll take a look myself

Hello again!
This is how my piloting URL looks like:
https://run.pavlovia.org/flaviozenteno/trialgjt/?__pilotToken=aab3238922bcc25a6f606eb525ffdc56&__oauthToken=71a9108069ee69a7770b1d4303c341b686838d3595f62343f6f2694293250041

I just added you as a developer in my experiment as well, thanks a lot in advance!

@wakecarter I feel like a real fool right now. When I added you as a dev I realised that the message said “added 1 hour ago”, which, of course, was not the case. Since the piloting token is valid for 1 hour I assumed that the reason for this was that the token already expired according to my timezone. Everything is fine now! Thanks a lot for your support and time, everything is working perfectly!

No problem. Does the pilot token work for a bit or does it fail straight away? How did you fix the issue?

The pilot token works perfectly now, I could run the whole experiment without any issues! All I had to do was to go 1 hour back in my PC’s clock to make it work.
