Connect-ExchangeOnline not working correctly

We currently have a kind of info page running on PSU, getting details of a user and are now trying to get some Exchange data like mailbox storage used.
For this we are running Connect-Exchange on ExchangeOnlineManagement:2.0.6-preview3 with authentication by Azure enterprise app.
Doing this works very rarely (just assume basically never), but returns an error most of the time:

“Object reference not set to an instance of an object. at UniversalDashboard.Execution.PowerShellExecutionService.ExecuteEndpoint(ExecutionContext context, AbstractEndpoint endpoint, List`1 nonTerminatingErrors) in D:\a\universal\universal\src\UniversalDashboard\Execution\PowerShellExecutionService.cs:line 219”

I’m happy with helping debug this and give you any info you need.

Product: PowerShell Universal
Version: 2.10.2


The location of this error is strange. Can you upload a log here or send it to
