I'm trying to upload a file to an existing password via API, using Powershell.
I try to get this code to work (from Passwordstates API Manual):
# PowerShell Request
$documentPath = "D:\Build-Specifications.txt"
$uri = "https://passwordstate/api/document/password/123?DocumentName=<DocumentName>&DocumentDescription=SomeDescription"
$result = Invoke-RestMethod -Uri $uri -Method Post -InFile $documentPath -ContentType 'multipart/form-data' -Header @{ "APIKey" = "<apikey>" }
Write-Host $result
But I get this error message:
Invoke-RestMethod: "An error has occurred., Value cannot be null.\r\nParameter name: plainText, System.ArgumentNullException
Any suggestions about what that can mean?
