With OME 3.0 we created a firmware baseline and did a successful firmware update for several M620/630 Blade servers. Cause we are running nearly 200 servers I´m looking for a Powershell Rest API script for starting this update job. Any idea about the syntax error in the script?

Error message:

Invoke-WebRequest : {"error":{"code":"Base.1.0.GeneralError","message":"A general error has occurred. See ExtendedInfo for more information.","@Message.ExtendedInfo":[{"MessageId":"CJOB4035","MessageId":"CJOB4035","RelatedProperties":[],"Message":"Unable to create or update the
