userManager.getUserByKey doesn't works with recently created user

[Malesys Elie]

I use the getUserByKey function of the UserManager in a scriptrunner groovy script to get an ApplicationUser instance. 

ApplicationUser supportTeam = userManager.getUserByKey("myOldUser");

return supportTeam.getDisplayName();

it works fine for any old user from any directory (internal or external)

if I create a new user and try this again

ApplicationUser supportTeam = userManager.getUserByKey("myNewUser");

return supportTeam.getDisplayName();

the user is not found (either on Internal or external directory), I get :

java.lang.NullPointerException: Cannot invoke method getDisplayName() on null object at Script2641.run(Script2641.groovy:67)

any Idea?

Regards,

Elie.

It works with a deprecated method : 

ApplicationUser myUser = ComponentAccessor.getUserUtil().getUserByName("myNewUser");

return myUser.getDisplayName();

but I would prefer to avoid using deprecated...

correct way to do it :

ApplicationUser supportTeam = userManager.getUserByName("myOldUser");

return supportTeam.getDisplayName();
