‘this.client.subscriptionid’ cannot be null. [Solved]
To fix all the above three issues, New-AzureRmResourceGroup: ‘this.Client.SubscriptionId’ cannot be null, New-AzureRmAppServicePlan : ‘this.Client.SubscriptionId’ cannot be null, New-AzureRmWebApp : ‘this.SubscriptionId’ cannot be null, we need to add the below cmdlets to the script
Get-AzureRmSubscription
Select-AzureRmSubscription -SubscriptionId xxxx4300-yyyy-xx18-9c9c-feaa72a5cbd1To get your subscriptionId, Login to the Azure portal and then search for the Subscription
Now click on the search result Subscriptions. Use the below SubscriptionId. In case of multiple subscriptions, choose the correct one.
Now, the complete script will be
Login-AzureRmAccount
Get-AzureRmSubscription
Select-AzureRmSubscription -SubscriptionId xxxx4300-yyyy-xx18-9c9c-feaa72a5cbd1
#Specify the Web app Name and Region
$mywebapp = "MyNewWebApp468"
$myloc = "Central US"
$myAppPlan = "MyWebApps"
New-AzureRmResourceGroup -Name mynewupdtrsggroup -Location $myloc
New-AzureRmAppServicePlan -Name $myAppPlan -Location $myloc -ResourceGroupName newresgroup -Tier Free
New-AzureRmWebApp -Name $mywebapp -Location $myloc -AppServicePlan $myAppPlan -ResourceGroupName newresgroup 
Note: Verify your subscription is ASM or ARM. Here, in this case your Azure subscription should be ARM.
If you have only an ASM subscription, you must add the ARM subscription.
This will fix all these above three errors.
