Intermittent errors with SMO expanding databases when they're in an AG

So this is hard to explain, there is a bug report for dbatools that I am also experiencing, where running Copy-DbaLogin works for most users most of the time, but pretty much every day I get at least one (different login, different database in error message) that fails out with the following error:

The target database ('DBNAME') is in an availability group and is currently accessible for connections when the application intent is set to read only. For more information about application intent, see SQL Server Books Online.

The normal path is that these databases are just skipped, but occasionally it seems like SMO tries to get in for some reason.

This is the get-error output

these are the commands that seem to throw the errors most often, but there is more info on the dbatools issue.

$destServer = Connect-DbaInstance -SqlInstance mssql1
$activeConnections = $destServer.EnumProcesses() | Where-Object Login -eq $newUserName
#or
$ownedDbs = $destServer.Databases | Where-Object Owner -eq $newUserName

Inizia leggendo il report dbatools collegato e tracciando i punti di ingresso segnalati: EnumProcesses() e la raccolta Databases, con il chiamante mostrato alla riga 324 di Copy-DbaLogin.ps1. Riproduci l'errore del gruppo di disponibilità e confronta entrambi i percorsi; il lavoro è concluso quando il fallimento intermittente è compreso e verificato rispetto al comportamento di SMO interessato.
