We alway have unknown resource errors when the experiment includes a Loop or Conditions with csv. file. We see the following error “when getting the value of resource: default.png”. But I don’t use this file name at all. Only when online experiments are conducted, this error arises. We use the lates…

I’ve discovered this issue with the latest version of PsychoPy, when images are set to update Each Repeat of Each Frame. A fix is on it’s way but in the meantime you could either upload an image called default.png (you might need to also add it as an additional resource) or set your images to consta…

Ah I see what this is… Essentially, if an :image: Image component’s image param (or a :movie: Movie component’s movie param, a :sound: Sound component’s sound param, etc.) is set to update each frame or repeat, then when the Image (or Movie or Sound or etc.) object is created it’s given a “safe init…

I unfortunately still have the same problem in 2023.1.3. Uploading an image called default.png or using resource manager didn’t help. Do you have any other idea on how I can solve this problem?

What does the rest of your experiment look like? Do you get the same error about failing to load resource?

Hi. I encountered this problem when I used nested loops with a condition file in the outer loop. There is no problem with an unnested loop or nested loops with simple repetition (i.e., no condition file to change parameters between loops). I am using v2014.1.5, online. Is there a work around?

Please could you show the error message and your image component? Personally I’ve been avoiding 2024.1.5 but I can’t now remember why. It might be worth trying 2024.1.4

Thank you for your quick help. I figured out what was happening. When I nested the loop, I had to modify the resource section of the .js file online. There I deleted the original line saying {'name': 'default.png', 'path': 'https://pavlovia.org/assets/default/default.png'}, and added a line to sp…

[image] Kosuke: When I nested the loop, I had to modify the resource section of the .js file online. Why did you have to edit the JS file. I (almost) never do that.

PsycoPy often failed to list all the files in the JS file resource section. But, strangely, I am not seeing this problem with my most recent versions of the experiment.
