This issue can be closed. AWS does not allow creating profiles with "/" in their name.

For example from boto3 API for creating profile:

The name of the instance profile to create. This parameter allows (through its regex pattern ) a string of characters consisting of upper and lowercase alphanumeric characters with no spaces. You can also include any of the following characters: _+=,.@-
