Hi All,

Can't seem to get my WHERE clause correct. Getting Invalid bind expression type of Object for column of type Id error. Here is the full class:
 

public class SubmitPublicationController {
    @AuraEnabled
    public static sObject getObjectById(ID anId) {
        
        system.debug('Entering controller');
        // Get the sObject token from the first ID
        Schema.SObjectType token = anId.getSObjectType();
        
        // Using the token, do a describe 
        // and construct a query dynamically. 
        Schema.DescribeSObjectResult dr = token.getDescribe();
        String queryString = 'SELECT Id, Name, Publication__c, Next_Object__r.Id, Previous_Object__r.Id FROM ' + dr.getName() + 
            ' WHERE Id = :anId Limit 1 ';
        
        system.debug('describe object result' + dr.getName());
        
        sObject objDBResult = Database.query(queryString);
       
      	List <Publication__c> pubsList = [SELECT ID, Publication_Submitted__c
                          	   FROM Publication__c
                               WHERE ID = :objDBResult.get('Publication__c')
                                         ];
        
        pubsList[0].Publication_Submitted__c = true;
        
        system.debug('pub ID='+pubsList);
    
        upsert pubsList;
        
        System.debug('ID is: ' + anId);  
        System.debug('objDBResult: ' + objDBResult); 
        
        return objDBResult;
       
    }
    
    

}
