While scheduling an errata for any client systems using Satellite API and curl, it fails with error "There was a problem in the JSON you submitted: XXX: unexpected token at '{errata_ids:'"}"

Issue

• When I try to install an errata using Satellite API and curl, there is an error.

# curl -X PUT -u username:password  -H "Accept:application/json" -H "Content-Type: application/json"  \
https://satellite.example.com/katello/api/v2/systems/dc8a11b7-32cd-4a0b-b23c-8f8c236d1309/errata \
-d {"errata_ids": "RHSA-2016:0010"}

->  {"status":400,"error":"There was a problem in the JSON you submitted: 784: unexpected token at '{errata_ids:'"}
