Solution

I can say you are using Microsoft Power shell utility.. which has different syntax. It is expecting a hash table type value for headers

@{<name> = <value>; [name = <value> ] ...}

If you really want it to be working in power shell, please go through power shell's Invoke-WebRequest syntax

When I ran this command in curl, it worked, no issues.

A tweak is if you have git installed in windows, you can set the command prompt to Git\mingw64\bin, and from there execute your curl commands
