Error handling and recovery

Exception caught and dropped

A catch block logs nothing and returns a default, so a failed write looks like success to the user and to the team.

Termsfault injection (making a dependency fail on purpose in staging to see what the user and the logs show) · API (the interface other software calls; tested directly, without the UI in between) · webhook (a message a provider such as Stripe sends to your server when something happens, like a payment)

Why AI-assisted code produces it

CodeRabbit measured error-handling gaps nearly 2 times more common in AI-co-authored pull requests over 470 open-source pull requests.

In the same 470-pull-request sample, cross-site scripting issues were up to 2.74 times more frequent in AI-co-authored pull requests; error-handling gaps were nearly 2 times more common and logic and correctness issues 75% more common.
