New-AzResourceGroupDeployment moving from File to Uri and lost passed arguments

Question

Working on some template automation and I'll need to move from deploying with local files to deploying with files from cloud storage. I've bolded the stuff that worked and now doesn't.

This works
New-AzResourceGroupDeployment -ResourceGroupName myrg -TemplateParameterFile .\ScalingParameters.json" -TemplateFile .\ScalingTemplate.json -vmInitialNumber 1 -hostpooltoken <System.Security.SecureString> -WhatIf

This doesn't
New-AzResourceGroupDeployment -ResourceGroupName myrg -TemplateParameterUri "https://mysa.blob.core.windows.net/wvdarmtemplates/ScalingParameters.json?sp=<stuff>" -TemplateUri "https://mysa.blob.core.windows.net/wvdarmtemplates/ScalingTemplate.json?sp=<stuff>" -vmInitialNumber 1 -hostpooltoken <System.Security.SecureString> -WhatIf

Is passing the additional arguments not supported with URIs of have I done something else wrong?

Thanks,
Joe

Have to read the documentation very carefully.
https://learn.microsoft.com/en-us/powershell/module/az.resources/new-azresourcegroupdeployment?view=azps-4.6.1

-TemplateParameterFile says:
To use the dynamic parameters, type a minus sign (-) to indicate a parameter name and then use the Tab key to cycle through the available parameters.

-TemplateParameterURI doesn't say that so it doesn't seem like it is supported.

I've moved on to -TemplateParamaterObject and adding my values there. Which will create a new set of questions.

(they really need a more general tag for new-azresourcegroupdeployment)
