Lambda create_function via local python SDK - Error The role defined for the function cannot be assumed by Lambda

Hi all, I want to create and update lambda functions from my local computer. I have created a role which has the permission AWSLambda_FullAccess. When I try to create and update lambda functions I get the error "The role defined for the function cannot be assumed by Lambda" The policy simulator shows: denied Denied by AWS Organizations.

Could you please give me a hint, how to solve this topic.
