Role chaining problem (aws console role-chaining)

Hi, Im trying to achieve the "role chaining" as in the https://aws.plainenglish.io/aws-iam-role-chaining-df41b1101068 i have an user admin-user-01 with policy assigned:

{
    "Version": "2012-10-17",
    "Statement": {
        "Effect": "Allow",
        "Action": "sts:AssumeRole",
        "Resource": "arn:aws:iam::<accountid>:role/admin_group_role"
    }
}

I have a role, which is meant for admin-user-01, with role_name = admin_group_role and trust policy =

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::<accountid>:user/admin-user-01"
            },
            "Action": "sts:AssumeRole"
        }
    ]
}

And it also has a policy:

{
    "Version": "2012-10-17",
    "Statement": {
        "Effect": "Allow",
        "Action": "sts:AssumeRole",
        "Resource": "arn:aws:iam::<accountid>:role/test-role"
    }
}

Then, i have another role, which is assigned for the role above (admin_group_role), with role_name = test-role and trust policy =

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::<accountid>:role/admin_group_role"
            },
            "Action": "sts:AssumeRole"
        }
    ]
}

But when i login as admin-user-01 into account, then switch to the role admin_group_role and then try to switch to role test-role

i get : Invalid information in one or more fields. Check your information or contact your administrator.

P.S everywhere <accountid> is the same, all of the roles,users,permissions are created in the same account ( what, i suppose might be the reason why i face the error )

What am i doing wrongly?
