JSON String in Apex: [{"CPQ_Total_Socket__c":"45","Id":"00102000004wiYUAAY"}]

Getting error :

System.TypeException: Invalid conversion from runtime type List to Map<String,ANY>

The clue is in the exception message.

When using JSON.deserializeUntyped a JSON object, like {"property": "value"}, is converted to an Apex Map<String, Object>. However, a JSON array, like [1, 2, 3] or [{...}, {...}], is converted to an Apex List<Object>.

Since your JSON is a JSON array at the outermost level parsing it will return a List<Object> but you try to cast it to a Map<String, Object> (I assume - you haven't shown the actual code that is getting the exception here) and hence the exception is raised.

As such you need to do:

List<Object> myObjects = (List<Object>) JSON.deserializeUntyped(jsonString);

Note that if your JSON string is correctly defined as always a list of Account records you could instead use:

List<Account> myAccounts = (List<Account>) JSON.deserialize(jsonString, List<Account>.class);

  • Hi Phil, Thank you for the response. But Even after usng Map<String, Object> getting same error. I have updated apex method with : Map<String, Object> output = (Map<String,Object>)JSON.deserializeUntyped(jsonString);.Unforutnately it is not working – surinder singh Feb 23 at 8:30
  • @surindersingh sorry that you misunderstood me. See updated answer. – Phil W Feb 23 at 8:37
