Maybe somebody can help me on what I am doing wrong?

**FOLLOWUP: I attached AdministratorAccess to role that was created by MWAA automatically **

how can I figure out which role was missing?

Answer

Hello,
I'm assuming that you're following the steps outlined in this documentation: https://docs.aws.amazon.com/mwaa/latest/userguide/call-mwaa-apis-web.html

It is important to note that the generated web-login-token is only valid for 60 seconds. Thus, it is important to access the Airflow URL with the token before it expires. If you're still facing the error even after ensuring timely login, the issue could be related to the IAM permissions. For the IAM execution role created during MWAA environment creation, it should already have the required permissions. Whereas, for login into Airflow UI, your own IAM role/user needs to have the `airflow:CreateWebLoginToken` permission as mentioned here: https://docs.aws.amazon.com/mwaa/latest/userguide/access-policies.html#web-ui-access

I hope this helps.
