Unhandled Internal Error when I try to open my experiment

saba · April 19, 2022, 1:17am

I am receiving the following error message when I try to open my experiment. Psychopy is saying it’s an “unhandled internal error” and to send the report to the developers. I just want to run it locally, not online. Can someone please help me?

I created the experiment on a different computer and an older version of Psychopy, but another one of my experiments, which is pretty much identical to this one (except for the excel file that determines the trials) runs fine on all versions of psychopy I’ve tried and on different computers. I’m not sure what’s wrong with this task.

Thanks,
Saba

Hi @saba, I was having the same issue and found a solution for this bug. I filed a bug report at Github which also contains a solution you could try. Hopefully it works for your too:

github.com/psychopy/psychopy

Crash on Startup when loading Pavlovia project (404 Project Not Found)

Problem: PsychoPy 2022.1.3 does not open .psyexp files for projects that have b…een pushed to Pavlovia before. I am running PsychoPy on Windows 11, but given the solution to this bug (see below), I assume that the issue should occur on all platforms. Error Log: This is the stacktrace from the "last_app_load.log" file when trying to open a respective psyexp file: ``` 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) File "C:\Program Files\PsychoPy\lib\site-packages\gitlab\mixins.py", line 112, in get server_data = self.gitlab.http_get(path, **kwargs) File "C:\Program Files\PsychoPy\lib\site-packages\gitlab\client.py", line 662, in http_get result = self.http_request( File "C:\Program Files\PsychoPy\lib\site-packages\gitlab\client.py", line 628, in http_request 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\app\psychopyApp.py", line 102, in <module> main() File "C:\Program Files\PsychoPy\Lib\site-packages\psychopy\app\psychopyApp.py", line 98, in main start_app() File "C:\Program Files\PsychoPy\Lib\site-packages\psychopy\app\psychopyApp.py", line 26, in start_app app = startApp(showSplash=showSplash) File "C:\Program Files\PsychoPy\lib\site-packages\psychopy\app\__init__.py", line 85, in startApp _psychopyApp = PsychoPyApp( File "C:\Program Files\PsychoPy\lib\site-packages\psychopy\app\_psychopyApp.py", line 215, in __init__ self.onInit(testMode=testMode, **kwargs) File "C:\Program Files\PsychoPy\lib\site-packages\psychopy\app\_psychopyApp.py", line 386, in onInit self.showBuilder(fileList=exps) File "C:\Program Files\PsychoPy\lib\site-packages\psychopy\app\_psychopyApp.py", line 599, in showBuilder self.newBuilderFrame(fileName=fileName) File "C:\Program Files\PsychoPy\lib\site-packages\psychopy\app\_psychopyApp.py", line 584, in newBuilderFrame self.builder = BuilderFrame(None, -1, File "C:\Program Files\PsychoPy\lib\site-packages\psychopy\app\builder\builder.py", line 208, in __init__ self.fileOpen(filename=fileName, closeCurrent=False) File "C:\Program Files\PsychoPy\lib\site-packages\psychopy\app\builder\builder.py", line 735, in fileOpen self.project = pavlovia.getProject(filename) File "C:\Program Files\PsychoPy\lib\site-packages\psychopy\projects\pavlovia.py", line 1253, in getProject project = session.gitlab.projects.get(name) File "C:\Program Files\PsychoPy\lib\site-packages\gitlab\v4\objects\projects.py", line 782, in get return cast(Project, super().get(id=id, lazy=lazy, **kwargs)) File "C:\Program Files\PsychoPy\lib\site-packages\gitlab\exceptions.py", line 306, in wrapped_f raise error(e.error_message, e.response_code, e.response_body) from e gitlab.exceptions.GitlabGetError: 404: 404 Project Not Found ``` Reason: I identified two bugs that caused the issue for me. **BUG 1:** too restrictive re.match pattern in pavlovia.py SOLUTION FOR BUG 1: In file: C:\Program Files\PsychoPy\Lib\site-packages\psychopy\projects\pavlovia.py LINE 1201 REPLACE `url = re.match("https:\/\/gitlab\.pavlovia\.org\/\w*\/\w*\.git", stdout)` WITH `url = re.match("https:\/\/gitlab\.pavlovia\.org\/[\w\.]*\/[\w\.]*\.git", stdout)` REASON FOR ERROR: My username contains a dot (frank.papenmeier), which was not covered by \w **BUG 2:** if projects.json in AppData\Roaming\psychopy3\pavlovia\ does not contain the project, getting the project info via gitlab fails, because user is not logged in, resulting in the "404 Project Not Found" error message SOLUTION FOR BUG 2: In file: C:\Program Files\PsychoPy\Lib\site-packages\psychopy\projects\pavlovia.py ADD AFTER LINE 1252 (and thus right before the following command "project = session.gitlab.projects.get(name)" that would otherwise fail: ``` if not session.user: nameSpace = name.split('/')[0] if nameSpace in knownUsers: # Log in if user is known login(nameSpace, rememberMe=True) ``` thus the corrected code at the respective section looks as follows: ``` if nameSearch is not None: name = nameSearch.group(0) if not session.user: nameSpace = name.split('/')[0] if nameSpace in knownUsers: # Log in if user is known login(nameSpace, rememberMe=True) project = session.gitlab.projects.get(name) return PavloviaProject(project.id) ``` I took the code block for logging into Pavlovia from an older version of pavlovia.py. This version also contained multiple additional ways of looking through further known users, which I thought is not required and thus left out.

I’ve been seeing this occasionally and I’m wondering whether the psyexp file now knows something about online repositories without checking the .git folder.
