Issue

I am getting the CosmosDB noSQL context using a Service Principal that has the "Contributor" role in the CosmosDB account. I am building a JSON document, based on your instruction in the "New-CosmosDbDocument" module When I am trying to execute the command "New-CosmosDbDocument -Context $cosmosDbContext -CollectionId $collectionName -DocumentBody $document" I am getting the following error from PowerShell:

$document = @" { "id": "$([Guid]::NewGuid().ToString())", "content": "Some string", "more": "Some other string" } "@

New-CosmosDbDocument -Context $cosmosDbContext -CollectionId $collectionName -DocumentBody $document

Write-Error : Cannot convert 'System.Collections.ArrayList' to the type 'System.String' required by parameter 'Message'. Specified method is not supported. At line:4 char:17 Write-Error $Error CategoryInfo : InvalidArgument: (:) [Write-Error], ParameterBindingException FullyQualifiedErrorId : CannotConvertArgument,Microsoft.PowerShell.Commands.WriteErrorCommand
