Experiment not working in Pavlovia

URL of experiment: experiencedotprobetask_forMen [PsychoPy]

Description of the problem: I uploaded an experiment in Pavlovia. The first step describing the experiment works but at the next step where it’s supposed to display characters and images based on an Excel file, it displays the error shown in the screenshot below.


Thanks for your help!


I can reproduce the error. It tells you that whatever you are trying to load and display has the wrong file format. PsychoPy is expecting an image or video, but is getting something else.

Did you by any chance name the condition file column pointing to your images image? image is a parameter of the image component.


You need to show us what you are trying to present and how you are doing it.

Best wishes Jens

Thanks Jens, indeed the file column was named “image”!

So I changed it with a different name and I now have the following error:
"Unfortunately we encountered the following error:

  • when setting the image of ImageStim: stimulus
  • when getting the value of resource: femmes/19_Conscientiousness_reduced
  • unknown resource
    Try to run the experiment again. If the error persists, contact the experiment designer.

“femmes/19_Conscientiousness_reduced” is the file it’s supposed to display and I don’t know why it doesn’t find it. I’ve try to indicate the path with “/” and "" but got the same error. What am I missing?


I am pretty sure that the file ** 19_Conscientiousness_reduced has a file extension. This is missing according to the error message.

You are working on a Windows computer? Windows does not display file extensions by default. Here is how to change it https://beebom.com/how-show-file-extensions-windows-11/

PsychoPy is “smarter” than PsychoJS in that it can handle missing file extensions.

Thanks a lot Jens, it’s working now :slight_smile:
