What Changed
Fixed a critical ARM template evaluation error in the Lookout Mobile Threat Detection connector that prevented deployment since version 3.0.3.
Security Impact (Visibility & Fidelity)
Deployments running Lookout 3.0.3 experienced complete connector creation failure due to an ARM expression parsing error. The APIKey field contained malformed bracket escaping that produced an invalid ARM expression during Sentinel connector instantiation, resulting in zero mobile threat data ingestion.
The error “expected token EndOfData and actual RightSquareBracket” blocked all new Lookout connector deployments — organizations installing this connector had no mobile threat visibility until this fix.
Technical Details
Changed APIKey field bracket escaping to match the pattern used by adjacent dcrConfig fields. After ARM deployment strips the escaping bracket, Sentinel now correctly evaluates the parameter expression to retrieve the customer API key for mobile threat data ingestion.
