Assign roles from Cognito OpenID IdP

[scott]

I am trying to set up AWS Cognito as the IdP for my Ignition project.
I can map most attributes but not the Roles.
the Roles field I am trying to map is an array e.g. [operators, supervisors]

Has anyone had similar issues with this? I get the feeling it's just a silly little error but not having any luck getting it working.

Edit: I have also tried mapping to the "custom:roles" field in case the array was the issue but this also does not map.

test login IdP respose data:

test login mapped attributes:

attribute mapping config:

Worked it out with the help of iControls support team.

It seems the colon was problematic, needed to wrap it in square brackets and double quotes and it parsed correctly.
