C4W3A3 Launch workspace (jupyter) failed

Launching the workspace (jupyter) does not work.

What to do about it?

Hi @dbodmer ,

I guess the error means your EMR Studio was created with subnets that are not in supported Availability Zones for launching the workspace.

I can see in this doc (How Amazon EMR Studio works - Amazon EMR) you can try to do the following

Go to EMR Studio → your Studio → Edit.
Check the VPC/Subnets attached to the Studio.
Add/select subnets in one of these AZs: us-east-1a, 1b, 1c, 1d, 1e, or 1f.
Make sure the EMR cluster and Studio can communicate through the chosen security groups.
Stop/restart the Workspace, or create a new Workspace after updating the Studio.

AWS notes that EMR Studio Workspaces launch in the Availability Zones associated with the Studio subnets, and restarting can move a Workspace to another subnet/AZ if configured.

Hi @dbodmer
I see you are in UTC+2 time zone. Just wondering - what AWS region you got when you did
cat ../.aws/aws_console_url ?
Was it us-east-1 at the very end of the link, or something else?

Also, why do you have 2 workspaces with the same name de-c4w3a1-studio-workspace?

Hi @juliak

us-east-1 indeed.

I don’t know why 2 workspaces.

Have you figured it out after @saou_a 's detailed comment, or do you need more help with it?

No need for more help. Thank you much.
