I have a List Group Members action to get the members of a security group >> then I am trying to build semicolon separated string for the members emails inside a compose action, as follow:-

johnjohn123_1-1698880893372.png

but i got this error;-

'The template language expression 'join(outputs('List_group_members_2')?['body/value']?['mail'],';')' cannot be evaluated because property 'mail' cannot be selected. Array elements can only be selected using an integer index.

Any advice?

Thanks

It is not possible to do in your way. To do:

  • declare a new variable of type array

variable array

  • use Apply to each to iterate of each users part of the group
  • check if the user has an mail, if true, append it to the array
  • use compose and join if you want to join the values with a comma:

join(variables('Emails'), ',')

You can also use a string variable and concatenate emails with a comma on each iteration.
