Unhandled internal error while trying to sync project

using Psychopy 2021.2.3 on a mac (Catalina).

It was working on my local machine, but encountered unhandled internal error trying to sync it (see below). I have just changed the size of everything from cm to ‘from experimental settings’.

I had encountered a weird thing that some of the keyboard objects would no longer accept ‘space’ whereas others would. In the ones that didn’t, 'space didn’t generate an error. Error was:

"Python syntax error in field ‘allowedKeys’: /space/

I need to get it online – help!!

UPDATE!!! it worked again if I entered ‘space’,‘space’ so I did that. But something is wrong here!

Cheers - Charlotte

That’s quite an old version now. I’ve come across that error before.

You should be able to just have ‘space’,
