That way the queueable had all the data it needed from all the trigger invocations when it fired (i. Using this way, you can create the chaining between the batches. The transaction is asynchronous of course but its one transaction. You already stated you have a unit test for the queueable's execute () that verifies the callout is. In contrast, the Limits. Since you used =, you're assigning the value false to PDF_Created__c, which in turn causes the. 1100.
