Steps to reproduce
I'm receiving error calling WebCmdlets (Invoke-WebRequest, Invoke-RestMethod) using PUT method if I don't explicitly set content-type header.
Calling
Invoke-WebRequest -Method PUT -Uri $someUri -Body $someBody
Returns Error in PowerShell 7.4.2:
Invoke-WebRequest: The given key 'Content-Type' was not present in the dictionary.
(the error is thrown before any network call is even started)
The exact same call runs OK with PowerShell 7.4.1 and all lower versions that I was able to test.
Running:
Invoke-WebRequest -Method PUT -Uri $someUri -Body $someBody -ContentType 'application/x-www-form-urlencoded'
also works OK - even with powershell 7.4.2.
I see the change in v7.4.2 release notes #21049
But, as I understand it, setting content-type (by request headers collection or -ContentType parameter) isn't required and omitting it shouldn't be any issue regardless of pwsh version. Content-type can be default ('application/x-www-form-urlencoded') or none depending on pwsh version.
According to the available docs:
https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.utility/invoke-restmethod?view=powershell-7.4#-contenttype
If this parameter is omitted and the request method is POST, Invoke-RestMethod sets the content type to application/x-www-form-urlencoded. Otherwise, the content type isn't specified in the call.
I could successfully call PUT requests without explicitly specifying Content-type just until pwsh 7.4.2.
Expected behavior
Invoke-WebRequest -Method PUT -Uri "http://fake" -Body "fake"
Invoke-WebRequest: Resource temporarily unavailableActual behavior
> Invoke-WebRequest -Method PUT -Uri "http://fake" -Body "fake"
