7.5 - Chromium mode [Error - An item with the same key has already been added]

Neel1 — Wed, 17 Dec 2025 13:05:09 GMT

while i was working on chromium mode in v 7.5, i noticed that in Dynamic wait - Two different element are added and while running i am getting error - An item with the same key has already been added.

When i use either of one - then no error is coming.

#v7.5 #chromiummode

I see the same thing. @Neel1 Have you reported this to Blue Prism Support already so it can be logged as a bug to be fixed?
