I’m getting the same error at the moment. Works fine in Psychopy. Have checked the image files and uploads all seem fine and are in /png format. They the same images have worked fine for me on another online Pavlovia experiment, so in my case not an issue with the files. For me the error changes with the resource specified changing (e.g. sometimes img 5 sometimes img 6 etc) suggesting some sort of general loading error? Very appreciative of any suggestions. Clearing cache and running using incognito don’t fix the issue. Is it possible to have too many or too large image files? Or too many nested loops?
Hi, all!! I’d like to add that I’ve been experiencing the same thing as described in katDyke’s post above. Like katDyke, moreover, I have followed pretty nearly all threads on this & similar topics, & have tried all the fixes suggested that don’t involve hard-core coding, and I still have no resolution to the problem.
If anyone has any advice/ suggestions, they’re very welcome!! Thank you all!!!
I have tried it with your kitten picture but no luck.
When I run your e2e_img experiment through the Explore section of pavlovia it loads just fine, however when I put your kitten picture into my study it is unable to load it.
Hi @ thomas_pronk :-). I replied a short while ago by messaging you directly, sharing my login ID & pw. I’m not sure whether my message went through, & can’t seem to find a log of my ‘sent’ messages. I’d much appreciate it if you’d let me know if you received my message.
@EJJ, I cloned your experiment and I can tell you what’s going wrong. The file has it’s extension in lowercase (img_kitten_png.png), but in the image stimulus you refer to it with uppercase (img_kitten_png.PNG).
I assume that this worked locally because in Windows, filenames aren’t case-sensitive (i.e. Windows doesn’t care whether you write img_kitten_png.png or img_kitten_png.PNG). But on the Internet, this does matter.
By writing img_kitten_png.png instead, my version of your experiment did work online.
Hey @cLEE, I think your issue has the same cause as @EJJ had. See my earlier post in this thread for a detailed reflection.
Applied to your experiment: I got an error message that referred to “Rita_008-Hop.png”, but the filename of this stimulus is “RITA_008-Hop.png”. Changing Rita to RITA wil probably fix the error.
@ thomas_pronk, You were right, thank you! I had looked up a similar error in a thread posted previously, and had gone back and verified the “.png” vs. “.PNG” issue, but had missed the big, white elephant on the sofa – the case mismatch in my filenames!! 8-< Thanks, awfully… but for your pointing that out, I’d probably still be looking for the proverbial nose on my face.
I’ll leave this here in case it helps anyone - I found my issue and it’s one of those annoying careless ones…
Psychopy didn’t care about case sensitivity in image file names in .csv file and so it ran fine, but…Pavlovia did and so wouldn’t load them. So if you’ve done everything else check case sensitivity very carefully!
Hi! I’m having a really similar issue, but I don’t see any discrepancies in my file names. The experiment runs fine on psychopy, but when I run it on Pavlovia, I get the error message: " * unable to download resource: …/…/InfinityThesisPracticeStimuli.xlsx (…/…/InfinityThesisPracticeStimuli.xlsx)"
The file is saved in the correct folders on my computer and can be downloaded from my WebIDE page. I just added you as a maintainer on my experiment. Here is the link from my dashboard page: ImplicitInfinitySC-SLOWTASK [PsychoPy]
Thank you in advance for any advice you might have!
I encountered the same error and found a solution after many attempts!
Removing " % " in my filenames solved the error.
So, if you encounter this kind of error, try removing special characters in your filename that might cause an error. I suppose some special characters might cause trouble in JS… (but not in Python)
Anyway the idea that this error may be related to filenames helped me solve the error. Thank you!
