I get an error when attempting to run my experiment

URL of experiment: https://run.pavlovia.org/cwas/sure2

Description of the problem: “error”: “[500] "unable to pull the project from the GitLab repository: Cmd(‘git’) failed due to: exit code(1)\n cmdline: git pull\n stderr: ‘Your configuration specifies to merge with the ref ‘refs/heads/master’\nfrom the remote, but no such ref was fetched.’" ( #None )”
I tried syncing again and this is what I get in return:Traceback (most recent call last):

The above exception was the direct cause of the following exception:

Hi There,

How do you produce this error? does it happen when you try and sync to pavlovia for the first time? If so are you signed into your pavlovia account in the application?


Hi Becca,

No, I am signed into psycho pie and when I attempt to pilot the experiment or run it that’s when I get the air

Hi There,

Could I please check:

  1. which button are you using to try and pilot/run the task.
  2. if this is pavlovia you might need to first sign into pavlovia and sync the project to pavlovia to make a project.

I am signed into pavlovia and have tried to both pilot and run the task in pavlovia

Hi Chris - your original error looks like it is generated from PsychoPy - not pavlovia - could you please share a screenshot of your psychopy project and show us which button you are using to pilot? If I click your link I get a 404 error - which implies the js did not compile and was not sent to pavlovia.
