Re: Passing a variable from an Angular paragraph to a Pyspark paragraph

[Jongyoul Lee <jo...@gmail.com>]

Hello,

It's been a long time but do you still have the same issue? I'm not sure
about the feature but someone is using the similar features in my
understanding.

Do you have any update?

Regards,
Jongyoul
