iDRAC9 with Lifecycle Controller Version 3.42.42.42 Release Notes

Header error while using Powershell for Redfish requests

Description: iDRAC RESTful API with Redfish displays an error stating unacceptable header specified in request for commands run on PowerShell. Unlike other REST API tools such as Python, CURL and Postman, the PowerShell Invoke-WebRequest command does NOT automatically add a header to REST requests; the header must be explicitly included by the programmer.
Workaround: You need to explicitly include a header while using Powershell for any type of Redfish request.
Systems affected: All systems supported by this release.
