Cannot Upload a File through the API with the synchronous Parameter

User PeterWells is experiencing a 500 error when trying to upload a file through the API using PowerShell with the synchronous=1 parameter. The API call works correctly without this parameter.

PeterWells provided the PowerShell code, which appears to be correct according to zogstrip.

The error log from /var/www/discourse/logs shows an error in uploads_controller.rb when creating an upload, but does not provide a clear cause for the issue.

Another user, adam_beers, is experiencing the same issue.

I have been trying to add uploaded files through the API using PowerShell. The call appears to work correctly when I use it to upload an image file, but if I try the same call with a synchronous=1 parameter added, it returns with a 500 error.

Based on a previous topic, I had hoped to use the synchronous feature to get the file url.

Can you share your PowerShell code? Or at least the HTTP request you’re making to upload a file?

The code looks like this:

$contentType=$r.BaseResponse.ContentType
$content=Get-Content $fileOut
$boundary=[system.Guid]::NewGuid().ToString()
$clientID=[system.Guid]::NewGuid().ToString()
$body=(
"--$boundary",
'Content-Disposition: form-data; name="type"',
'',
"image",
"--$boundary",
"Content-Disposition: form-data; name=""files[]"" filename=$imageName",
"Content-Type: ""$contentType""",
'',
"$content",
"--$boundary--"
) -join "`r`n"
$tempURL=$urlTo+"uploads.json"+$loginTo+"&client_id=$clientID&synchronous=1"
$resp=Invoke-WebRequest $tempURL -Method Post -ContentType "multipart/form-data; boundary=$boundary" -Body $body -Verbose

$urlTo is the url for the site, $loginTo is the APIkey and username. The $r at the top is the response from downloading the image from another site to a file called $fileOut

Code looks correct. What does your.discourse/logs show when you get the 500?
