Powershell Invoke-RestMethod：远程服务器返回错误：(413) 请求实体太大

Question

This is in continuation to "Unable to ingest JSON data into Azure Event Hub" issue raised by me.

I wrote the below powershell script to get the JSON data from an API endpoint and then move this data without any format change to Azure Event Hub. When I run this I am getting the below error:

$url = "https://data.melbourne.vic.gov.au/resource/vh2v-4nfs"
$apptoken = "n8lQcUZROasdh9fSSMuV"

# Set header to accept JSON
$headers = New-Object "System.Collections.Generic.Dictionary[[String],[String]]"
$headers.Add("Accept","application/json")
$headers.Add("X-App-Token",$apptoken)

$results = Invoke-RestMethod -Uri $url -Method get -Headers $headers

$resultsJSON = $results | ConvertTo-Json

#Write-Host $results

$method = "POST"
$URI = "https://EHNS.servicebus.windows.net/eh-streetparking/messages"
$signature = "SharedAccessSignature sr=EH.servicebus.windows.net%2feh-streetparking&sig=erTfoeVLiWrOk9aDsU%3d&se=1605994&skn=eh-sap-streetparking"


# API headers
$headers = @{
            "Authorization"=$signature;
#            "Content-Type"="application/json;type=entry;charset=utf-8";
            "Content-Type"="application/json";
            }


# create Request Body

# execute the Azure REST API

Invoke-RestMethod -Uri $URI -Method $method -Headers $headers -Body $resultsJSON

#Error

Invoke-RestMethod : The remote server returned an error: (413) Request Entity Too Large.

How do I resolve this error? Are there any better scripting language and/or practices which I can adopt while writing above sort of scripts?
