I have written a trigger helper method that converts to contact and associates the contact with an existing account. The contact owner becomes the owner of the account as shown in this snippet

Now I dont know how to cover this assignment -  c.OwnerId = c.Account.OwnerId;

I am getting the error :

Error occured while converting the Lead to a Contact in convertLeadToContact methodSObject row was retrieved via SOQL without querying the requested field: Contact.Account

Any ideas?

Thanks

contList =  [select Id, OwnerId from Contact where Id IN :cidList];// contains the list of created contacts after conversion
			
            //update contact owner with related account owner
            if(cidList.size() > 0){
                           
                for(Contact c : contList){
                      c.OwnerId = c.Account.OwnerId;
                            
                 }
                
                update contList;
                }
