Knowing how to do this will result in better more consistent error messaging for your users and higher quality and easier to maintain code! Exception handling is often overlooked in Salesforce development and it's a shame because it brings so much to the table that to create higher quality user experiences that you otherwise wouldn't have.

While I do point it out around the 21:30 mark in this video, one thing I should have focused on more is how critical it is to do exception handling when building integrations. Using exception handling in integrations gives you the ability to retry your callouts if they failed, log failed callouts to be re-attempted later, and more. Please please PLEASE make sure to use exception handling when building integrations!

Great video! One question - I use a logging framework for exceptions in Apex and store the data in an object. How can I build something similar for LWC. Do I need to make a server call from finally block to log that exception in the object?? Please let me know

is it possible to display a report that shows all the apex exceptions that have happened? similar to a flow interview where you can see all your errors

How would you use add error on a record if your trigger is bulkified?

Talking about the mentioned scenario where the user could receive more than two exception messages, is it really possible, as the message is created in Apex? I mean, when an Exception is thrown, possible following ones won't be able to be reached. Thus, only one exception message would be sent to LWC, for instance. Am I wrong?
