Boundary system logs are truncated, and how can I debug the internal errors?

Hi, I have setup boundary on AWS. However, when I try to create Boundary resources (boundary-reference-architecture/deployment/aws/boundary at main · hashicorp/boundary-reference-architecture · GitHub) with the codes here in the Github example, it shows me the errors below.

Error: error calling create role: {"status":500, "code":"Internal", "details":{"error_id":"Bcqrew3GZP"}}
Error: error creating scope: {"status":500, "code":"Internal", "details":{"error_id":"s8H7SQ78il"}}

To debug the issue, I ran sudo systemctl status boundary-controller in the controller machine, resulting in the messages below.

I have 2 questions. The messages are truncated, and how can I see the full messages? Second, how should I debug the errors such as [ERROR] controller: internal error returned: error id=cufwDpcAeR error="unable to create scope?

Any help would be very greatful!
