Assigning machines to Maintenance config is failing

Question

am not sure what mistake I have done, created the maintenance config successfully but while creating assignment giving following

Command I have used:

PS /home/user> $mc=Get-AZMaintenanceConfiguration -ResourceGroupName UE2PRD01RESOURCEGROUP -Name Dr01MainteanceConfig

PS /home/user> New-AzConfigurationAssignment -ConfigurationAssignmentName $mc.Name -MaintenanceConfigurationId $mc.Id -FilterLocation eastus2euap,centraluseuap -FilterOsType Windows -FilterTag '{"EnvironmentCode" : ["Dev01"] }' '{"EnvironmentType" : ["Development"] }'

New-AzConfigurationAssignment: 'resourceType' cannot be null.

PS /home/user> New-AzConfigurationAssignment -ConfigurationAssignmentName $mc.Name -MaintenanceConfigurationId $mc.Id -FilterLocation eastus2 -FilterOsType Windows -FilterTag '{"EnvironmentCode" : ["Dev01"] }' '{"EnvironmentType" : ["Development"] }'

New-AzConfigurationAssignment: 'resourceType' cannot be null.

PS /home/user> New-AzConfigurationAssignment -ConfigurationAssignmentName $mc.Name -MaintenanceConfigurationId $mc.Id -FilterLocation eastus2 -FilterOsType Windows -FilterTag '{"EnvironmentCode" : ["Dev01"] }' '{"EnvironmentType" : ["Development"] }' -Debug

@sns - Thanks for reaching out to us.

Looks like filter tag that you are using is wrong, please try the below command.

New-AzConfigurationAssignment -ConfigurationAssignmentName $mc.Name -MaintenanceConfigurationId $mc.Id -FilterLocation eastus2 -FilterOsType Windows -FilterTag '{"Env": ["ABC"], "XYZ": ["PQR", "ZZZ"]}' -Debug

Hope this helps. and please feel free to reach out if you have any further questions.
