Streisand on Amazon Error

[Keridoo]

During trying to setup Streisand on Amazon I get the following error message. What's going wrong? How can it be fixed?

`TASK [ec2-security-group : Create the EC2 security group] ********************************************************
An exception occurred during task execution. To see the full traceback, use -vvv. The error was: ClientError: An error occurred (AuthFailure) when calling the DescribeSecurityGroups operation: Authorization header or parameters are not formatted correctly.

By the way, I used the following tutorial to set up the "AWS IAM role and policy setup":
https://github.com/StreisandEffect/streisand/blob/master/documentation/AWS.md

When using an AWS IAM role with full administrator access, I don't run into this problem. However, I receive the following error.

After getting rid off snapd, I could continue until I encountered:

How can I skip this step?

Please let me know if more information is needed.

Many thanks for your support!
