jetbrains.buildServer.serverSide.auth.AccessDeniedException - Trying to run a build from inside another build using REST API

This is the command I'm using:

   curl -s -u "%system.teamcity.auth.userId%:%system.teamcity.auth.password%" %teamcity.serverUrl%/httpAuth/app/rest/buildQueue --request POST --header "Content-Type:application/xml" -d "<build><buildType id=\"General_NasSync\"/></build>"

This results in an error:

[10:09:45]    Responding with error, status code: 403 (Forbidden).
