JsonMappingException: Can not construct instance of org.springframework.security.core.GrantedAuthority
When populating the authorities field in a JSON/YAML edu.wisc.uwss.local.userDetailsLoader.resource, like so:
[
{
"username": "admin",
"password": "admin",
"fullName": "Amy Administrator",
"firstName": "Amy",
"lastName": "Administrator",
"authorities": [ "SERVICE" ]
},
...
]Observe the following stacktrace:
Caused by: com.fasterxml.jackson.databind.JsonMappingException: Can not construct instance of org.springframework.security.core.GrantedAuthority, problem: abstract types either need to be mapped to concrete types, have custom deserializer, or be instantiated with additional type information
