Getting 415 error when uploading csv file via powershell

[John Welch]

As the title says, I have a powershell script:

#boilerplate to display a file chooser dialog

Add-Type -AssemblyName System.Windows.Forms

$fileBrowser = New-Object System.Windows.Forms.OpenFileDialog -Property @{ 

     #InitialDirectory = [Environment]::GetFolderPath('Desktop') 

     RestoreDirectory = $true

     Multiselect = $false

     ShowHelp = $false

} 

#display the file browser so i can pick the file I want

$null = $fileBrowser.ShowDialog()

#set filepath to var

$attachmentPath = $fileBrowser.FileName

#set content type

$content="text/csv"

#auth header for confluence using PAT

$headers = @{'Authorization'="Bearer <PAT Token here>"

'X-Atlassian-Token'="no-check"}

#page URL

$theURL = "https://<domain>/rest/api/content/<page ID>/child/attachment"



#post command

Invoke-RestMethod -Headers $headers -Uri $theURL -Method Post -InFile $attachmentPath -ContentType $content

When I run that script, I get a 415 error:

Invoke-RestMethod : The remote server returned an error: (415) 415.

if I try to use Put instead of Post, I get a 405, method not allowed. 

it's definitely a CSV file i'm uploading, so I'm a bit mystified here, any help would be greatly appreciated.
