Custom Actions documentation

Thanks, can both of you send the backend logs and frontend logs of what you’re seeing when this fails?

It doesn't fail as such. You just can't move the slider. There's no logging of any type or JS errors in console.
I've worked around it by editing the setting in the Metabase database.

Nothing in the backend as well?

No, there's nothing. You can't click anything, so nothing is happening.
