I am new to Salesforce Apex coding and I am getting this null pointer exception error when i try to run a schedule batch. Please help me as i am unable to understand the mistake i made. The code is working on insert records, but it fails when i try to run a schedule batch. The issue is related to passing parameters when calling the batch class in scheduled batch but i do not know how to do that?
