Can't Resolve a Syntax Error in Online Experiment

URL of experiment: SRD1 [PsychoPy]

PsychoPy version: 2024.1.5
Computer: Windows 11
Browser: Chrome

Description of the problem:
I have been running my experiment online for about 3 years and it was running smoothly. Recently, I needed to change the completion redirect URLs, and when I synced the experiment online, it is stuck on “initialising” screen. Both the Chrome debugger and the Psychopy Runner said it’s a syntax error. The line in the code they referred to was the code to set the output file name. I had a custom one written in, but have deleted it, since it doesn’t work on online experiments anyways. Now, they both say that the syntax error is an unexpected “)” in the same line. I have no idea how to fix this.

Relevant screenshots of everything as it stands right now:

I would start by putting the default Data filename back

u'data/%s_%s_%s' %(expInfo['participant'], expName, expInfo['date'])

The error is because you have a blank after the second +

Thank you, it’s fixed! I don’t know why I didn’t think of the fact that there might be a default there.
