Sending post though Powershell curl

For some reason when request is sent through Swagger it goes through without any issues

But when I try to do the same thing with powershell I get 400

curl -Method Post -Uri "http://localhost:32774/WeatherForecast" -Headers @{ accept = '*/*';"Content-Type" ="application/json" } -Body "test"

What can I do to fix it?
