Description of the problem:  
I am using PsychoPy 2022.2.2. When attempting to sync the experiment to Pavlovia from the builder, I received the following messages:

Traceback (most recent call last):  
File “C:\Program Files\PsychoPy\lib\site-packages\gitlab\exceptions.py”, line 304, in wrapped\_f  
return f(\*args, \*\*kwargs)

raise gitlab.exceptions.GitlabHttpError(  
gitlab.exceptions.GitlabHttpError: 404: 404 Project Not Found

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

Traceback (most recent call last):  
File “C:\Program Files\PsychoPy\lib\site-packages\psychopy\projects\pavlovia.py”, line 663, in project

raise error(e.error\_message, e.response\_code, e.response\_body) from e

During handling of the above exception, another exception occurred:

raise KeyError(f"Could not find GitLab project with id {self.id}.")  
KeyError: ‘Could not find GitLab project with id 241365.’

I would really appreciate your kind help.

Hi @shenqidu,

it seems like the syncing didn’t work because for some reason, your project couldn’t be found. I don’t know what you did, but I’d guess that it could be the case if you tried uploading your experiment for the first time and haven’t created a project on Pavlovia/Gitlab yet. If this is the case, check this post on how to create a project: [Launch your study on Pavlovia.org — PsychoPy v2022.2.2](https://www.psychopy.org/online/usingPavlovia.html)  
If you already have a project, you could also try emptying your browser’s cache & to sync again or (if this doesn’t work either) to move your experiment to a new file on your computer and to upload it as a new project.

I hope this helps! 🙂

Merle

Hi Merle, thanks for your reply!  
I initially succeeded in syncing from the Psychopy builder to the PavloviaI. But when I modified the program in builder and tried to sync again, an internal error occurred. I have my project on the PavloviaI, but the code is empty. I tried to put the folder in another location and delete online project, but the internal error still occurs. I want to try to log in to another PavloviaI account, but I can’t get the login window to pop up on the Psychopy. I don’t know how to work it out.

Thank you again for your kind help.
