How investigate fly 500 internal server error

I’m investigating Concourse for use in my company but not getting very far with the Stark and Wayne tutorial. When I try “fly -t tutorial execute -c task_hello_world.yml” on the 2nd page it just comes back with:

error: ‘uploading task-hello-world’ failed: Unexpected Response
Status: 500 Internal Server Error

The version of Concourse is 5.6.0. How can I investigate this further? I can see it’s a post request to /api/v1/teams/main/artifacts?platform=linux which is falling over.

Thanks for any help!

Do any other fly commands work against your Concourse?

Thanks for the response! Investigating Concourse is now in the background for the moment, this particular issue I did get past by using a different version of Linux.
