Having issues with commands in Butler to add checklist items as tasks

[Briggs]

I keep getting the error "CANT_PARSE_COMMAND" when trying to do this. I've followed the help articles with screenshots on how to set this up. Basically I want to have a master checklist of all items, and then when that card is moved into a certain list such as "Do This Week" that those checklist items also become linked cards. I'm including a screenshot of what I'm doing- it must be wrong, because I keep getting that same error.

Hi @Briggs

I'm an engineer on the Trello Automation team and I took a look at what's going on here. For some reason the command isn't being sent to our servers correctly and we suspect that a browser extension is at fault.
Could you try opening an incognito window (or temporarily disabling your extensions) and then create the command again?

Wow, that worked! Should I do all my automation in incognito because of this weird browsers extension issue?

I also tried to do it as a button, which also failed.
