SageMaker Studio credentials errors

Question

I can no longer view projects, pipelines or create new note books. The complaint appears to be credential related.

Failed to launch app [None]. Error when retrieving credentials from container-role: Error retrieving metadata: Received non 200 response (400) from ECS metadata: ResourceNotFoundException

Has anyone run into this before? Nothing should have changed in the environment.

Additionally, when I view my user in SageMaker console, it doesn't have an arn listed under the Execution Role section:

Editing the user and re-saving it doesn't populate the role either. The role exists in IAM and it appears in the wizard when I edit the user details:

Answer 1

Creating a more intuitive UI based solution:

1. go to sage maker:

2. go to the affected domain:

3. go to the affected user profile

4. delete this.

then relaunch studio as you normally would. If you deleted the right server it should say that it's creating a new one. Your files will remain.
