TypeError: unhashable type: ‘list’

Before the fire, the experiment was operational on Pavlovia, and Psychopy run well on my computer. Now, I can open Psychopy builder, see my experiment, modify it and run it, but I get this error message even without attempting to sychnronise with Pavlovia, and also I cannot synchronise. Please help, I’m running out of time. My student does not have this problem, so I concluded it is not related to the fire.

Thank you,

Leila

Try disabling your sliders

Thanks for the suggestion. Still, when i try to synchronize, I get a Gitlab authentification error. It seems that there’s more than one problem.

These are the two last lines:

http_request
gitlab.exceptions.GitlabAuthenticationError: 401: 401 Unauthorized

When did you create your Pavlovia account?

5

It was in january I think. Maybe early february. I can access my account but I can’t snychronize or re-create an experiment.

6

This may be related to the fact that we’re running on a snapshot from Jan 4th. Hopefuly everything will be sorted early next week.

Actually this was way before. It is an institutional licence. I just started using it in january. Sorry about that. Anyway I’ll just wait monday then, thanks again!

Hello,
I am having the same problem. Did you solve the problem, if so, could you tell me how?
Thanks in advance.

Are you getting the error message TypeError: unhashable type: ‘list’

I suspect that this is because you are using a variable which PsychoPy sees as a list in context which expects it to be a number or text.

What variables might this be?

Hello,
Thanks for your very quick response.
I am coppying the error that I am getting. Not exactly the same but mostly. I am very new at this but this error occurred suddenly some time after I was trying to syncronyize the experiment with Pavlovia. But not only this when I just open the Psychopy I am getting an another series of errors. I upgraded Psychopy but nothing changed.

Hello,

I’m having the same error message each time I am trying to upload my experiment on Pavlovia. Did someone solve the problem ?

I am using the last version of Psychopy, on Macbook Pro Touch Bar (BigSur) or on Windows 10 and I can’t upload on Pavlovia with both. (I am very new to this)

Thank you
