New-AzureRmResourceGroupDeployment Command not recognizing the JSON paramaters file - powershell

Question

I have a JSON parameters file that looks like this.
"parameters": {
"field_1": {
"value": "abc"
},
"field_2": {
"value": 123
},
and I am using the below command to create resources in Azure
New-AzureRmResourceGroupDeployment -ResourceGroupName $resourceGroupName -TemplateFile $templateFilePath -TemplateParameterFile $parametersFilePath
when I run it, for some reason it's not recognizing the parameters that are in the parameters file. It asks me to enter the parameters individually in powershell and then after I enter all of them I get the below error:
New-AzureRmResourceGroupDeployment : 4:07:58 PM - Error: Code=InvalidDeploymentParameterValue; Message=The value of deployment parameter 'parameters' is null. Please specify the value or use the parameter reference. See
https://aka.ms/arm-deploy/#parameter-file for details.

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [New-AzureRmResourceGroupDeployment], Exception
+ FullyQualifiedErrorId : Microsoft.Azure.Commands.ResourceManager.Cmdlets.Implementation.NewAzureResourceGroupDeploymentCmdlet
I am not sure what I am doing wrong. Any help would be greatly appreciated.

Well, it should not recognize it, if you look at the Azure Quickstart templates repository, most of those have parameter files, all of them have a proper structure, while yours don't, here's how a proper parameter file looks like:
{
"$schema": "http://schema.management.azure.com/schemas/2015-01-01/deploymentParameters.json#",
"contentVersion": "1.0.0.0",
"parameters": {
"adminUsername": {
"value": "ghuser"
},
"adminPassword": {
"value": "GEN-PASSWORD"
},
"dnsLabelPrefix": {
"value": "GEN-UNIQUE"
}
}
}
