Hi.
Get-RDMOauthToken stopped working since version 2026.1.0 at least, but i tried with the latest 2026.1.2 as well.
PS C:\Users\to-fre> Get-Command -Module Devolutions.Powershell | where {$_.Name -match "Get-RDMOAuthToken"}
CommandType Name Version Source
----------- ---- ------- ------
Cmdlet Get-RDMOAuthToken 2026.1.2 Devolutions.PowerShell
PS C:\Users\to-fre> New-DSSession -BaseURI $DSServerUri -UseOAuth
PS C:\Users\to-fre> Get-RDMOAuthToken
Get-RDMOAuthToken: The type initializer for 'System.Text.Json.JsonSerializer' threw an exception.PS C:\Users\to-fre> Import-Module -Name Devolutions.PowerShell -requiredVersion 2025.3.4
