from local to online - isn´t working

KiKl13

Hello community,

I was wondering if you could help me with the following problem regarding a study I have set up. First I have created a study locally. This worked without problems. Then I went through the steps that are explained here: https://www.jatos.org/Deploy-to-a-server-installation.html

I downloaded the study as jzip and imported it in the Jatos server. This has also worked so far.

However, when I run the study, absolutely nothing is displayed. What could be the reason for this? I made sure that I do not have another folder with the same name (I have read that in another problem feed as a solution).

Thank you!

Hi, Kikl13,

The first thing to do would be to go to your browser's developer tools. (e.g. in Chrome, View -> Developer -> Developer Tools) and check whether there any error messages logged in the console. Can you check what you get and copy it here? That will give us a hint of where to look.

Also, where is your server?

Hi Elisa,

I hope the attached screenshot is what you need?

I am using the server of my university HU-Berlin.

Thank you so much for your help!

Hi!

It looks like you have a problem with your paths. Can you send me your study and I'll have a look?. If you don't want to post it to everyone here just send it to me personally. But you can't attach the jzip file here in this forum - you have to use a file sharing service (e.g. Google Drive, Dropbox).

Best,

Hi,

I looked at your study. To fix your problem, simply go to your study properties (click on the button Properties on the dark-blue study bar), and change the information in the field: "Study assets directory name"

This is the name of the folder that contains all your study files. You had named it jsPsych-6.1.0. I suspect the special characters were messing things up. Give it a different name, (e.g. robotmerkmale). When you import a study into JATOS, this will create a directory in your filesystem. So it makes sense to name this directory with your experiment's name, not the name of the toolbox you used to program it.

When I changed that property (and then clicked OK on the popup giving me the option of either renaming the study assets folder -without creating a new directory) it worked for me. I recommend you first do this locally. Then export the study and import it again into your HU server. That should work, but let me know if it doesn't.

Hi Elisa,

thank you for your help! So while I was implementing your suggestions, I noticed that I named the folder with the plugins "jsPsych-6.1.0". Emphasis is on the capital P. In my study code, I was only using jspsych-6.1.0 (with small p). After I fixed it, it worked finally. I still don't understand why it worked locally and only became a problem online. But at least it works now :)

Thanks for your help and time!

Ah, that makes sense. We've had this before with image extensions (.PNG vs .png). You're using two different OSs on the server and your local computer and they can have different restrictions and case-sensitivities. In any case happy to hear it works.

Ah, I guess on your local computer where it worked fine you have Windows which is case insensitive when it comes to paths. And on your remote JATOS server you probably have some kind of Linux which is case sensitive and didn't accept your path.

Nice that it worked now :)
