puppet-dashboard responds with 406

[JoeDog]

I have the dashboard running on RHEL 8 with puppet 6.28

No data is being handled by the dashboard. When I check the puppetserver.log I see this:

2023-03-14T13:54:38.058-04:00 ERROR [qtp2094954710-50] [puppetserver] Puppet Unable to submit report to http://host.domain.com:3000/reports/upload [406]

I'm not sure if the dashboard has been tested with puppet > 5; maybe the report format has changed.

I captured the report and posted it to the dashboard with siege. I got this error:
Unexpected error while processing request: RangeError

The report I captured looks like this:

Am I SOL?
