500 internal Server Error when trying to update an attachment using Powershell

Julien Henning

I want to update an json file in confluence using the Api and Powershell 

---

$pageId = "2226721108"  # Replace with the actual page ID

$attachmentId = "2238705975"  # Replace with the actual attachment ID

$apiUrl = "https://HereIsOurServer/confluence/rest/api/content/$pageId/child/attachment/$attachmentId/data"

$proxy = "ourProxy "

$headers = {

    "Authorization" = "Bearer $authToken"

    "X-Atlassian-Token" = "nocheck"

    "Content-Type"="multipart/form-data"

}

$body ={

    "file" ="StatusTestclients\JiraUpdateTestClients\result.json"

    "minorEdit"=$true

    "comment"="new"

}

# Send the POST request to update the attachment file

Invoke-RestMethod -Uri $apiUrl -Headers $headers -Method Post -Body $body -Proxy $proxy

---

And here the error i get 

---

@Julien Henning Welcome to the Atlassian community

From the error you are seeing, it would tend to indicate that either the parameters are incorrect or that the json package is incorrect.  Are you able to successfully make any other API calls?
