My Mule application was working fine and all of a sudden i started getting the below exception.
Open quote is expected for attribute "classId" associated with an element type "object". ERROR 2017-09-20 21:12:22,455 [pool-11-thread-1] com.microsoft.aad.adal4j.AuthenticationContext: [Correlation ID: xxxx-xxxx-xxxxxxx-xxxx] Request to acquire token failed. org.xml.sax.SAXParseException: Open quote is expected for attribute "classId" associated with an element type "object".
Any help would help.
