Unique list item permissions with REST api invalid URL

New Contributor

Hello all,


I'm working on a simple flow that is currently with an error of invalid URL.

The steps are: From a List item I get a client name which I use to create a group. After that I break the item permissions, get the group id and create a variable for PrincipID and provide read-only permissions for that item.


It is not working and I have no clue why. With a pre-created group it works. Here are some prints.










Any suggestion or clue on what I am doing wrong? I have the same process as you can see for another group that already exists and it works.


Thank you in advance.

I solved this, if anyone has a similar problem:

- Inicialize variable as integer
- Pass variable to a string

Thank you.
