LC 9.6.7 and Applescript

[jbv at souslelogo.com]

Hi list,

I am trying to use an old stack made with LC 8.1 community that used to 
work fine on Mac OSX 10.11.
Now I am with LC 9.6.7 on OSX 10.15.
The stack features some AppleScript commands such as :
  tell application "Google Chrome" to set URL of active tab of window 1 
to "https://www.domain.com"

But now I get an execution error in LC 9.6.7, while those commands run 
fine in the script editor
utility.
I am not really familiar with the relationship between LC and 
AppleScript.
Where should I look to fix this issue ?

Thank you in advance.
