Problem with Experiment in Pavlovia

Online experiments
#1

URL of experiment: https://gitlab.pavlovia.org/himynameisclara/ss_training_day1
Project ID: 4260

Description of the problem: I have created an experiment in PsychoPy which is running well on my machine. I uploaded it to Pavlovia from PsychoPy however, when I press Launch on Pavlovia I get a 403 Forbidden Nginx error.

Has anyone encountered the issue before? And how did you resolve it please?

Thanks in advance!

It looks like your experiment didn’t sync the files properly. When you press sync in PsychoPy what happens?

#3

It gives me the following:

Synchronising…
Pulling changes from remote…
Already up to date.
done
Pushing changes from remote…
done
Successful sync at: 15:18:52, took 1.138s

#4

I don’t understand. That sounds successful, but only one file is getting pushed to the server. I’m at a loss as to why this is occurring I’m afraid.

#5

When you synced the files, did you write something in the ‘Summary of changes’ dialogue box, or did you just press OK, leaving the dialogue box blank?

#6

I left the dialogue box blank. Should I write something?

#7

I will try and upload it from a different machine and see if I have any luck with that! Thanks :slight_smile:

Yes, as @unagi_pie suggests, you will need to write a commit message otherwise the sync will fail. You should see an error in your console (if Coder is open), such as

  File "C:\Users\lpzdb\psychopy\psychopy\app\builder\builder.py", line 2379, in onPavloviaSync
    pavlovia_ui.syncProject(parent=self, project=self.project)
  File "C:\Users\lpzdb\psychopy\psychopy\app\pavlovia_ui\project.py", line 477, in syncProject
    outcome = showCommitDialog(parent, project)

Thanks for the response. Unfortunately I tried uploading again from a different device, and also wrote a commit message but no success :frowning:

#10

Would you mind sharing your experiment and associated files so we can see if anything is happening with files?

#11

That would be of great help! Should I send them to you via email? There’s quite a few image and sound files.

#12

Great, you can just send a zip file either on this post, or by direct message on here.

himynameisclara, Have you solved this issue, if yes pls share the solution. I am experiencing the same problem

Hi @Lukamark, what is your actual issue? Can you post a link to your online study so we can see the error?

#15

The reason was trivial. I haven’t exported HTML before uploading study to Pavloivia. Shame on me!

#16

Hey, I am facing the same 403 error when I activate and launch. I tried everything like uploading again after deleting git files.

I sync from psychopy, go to pavlovia (activate and launch)

Am I missing some important step?

#17

Hi, I have been encountering the same issue. Did anyone find out an solution for it?
Might this be due to the fact that I am trying to upload the .py code file and not the .psyexp file?

Thank you in advance.

Hi @rob-linguistics13, you need to have exported the HTML and JavaScript from Builder in order to have a valid PsychoJS task that will run on Pavlovia. Take a look at these guidelines for running online studies.

#19

Thanks! I had already read the web page you posted, but I did not understand that only experiment from the Builder may be uploaded on pavlovia.org. I’ll try and see if this solves the issue.

#20

Any files can be uploaded and from command line as well, but if you want to run a task from Pavlovia, you need the html and JavaScript that Builder exports
