RMD054 — A post-commit callback threw, and the failure was swallowed

This one is reported only from a production build, and it is the only code on this page that is. In development the same failure goes to the console with the error object attached, which is more than a record can carry and better to read.

Commit-level work is isolated the way a @mounted is: one piece of it must not stop the rest. It has no component to hand a failure to — that is what makes it commit-level rather than a lifecycle callback — and it is not rethrown, because it runs while a commit may already be unwinding and a throw there would replace the real error with a metadata one.

The consequence is a swallowed exception, and in production nothing said so. Nothing renders differently, nothing logs, and whoever wrote the callback has no way to learn it never ran. So if your app has installed a collector, the fault is reported to it.

The record carries the code and nothing from the error. The message on a thrown error is written by whatever threw — your code, or a library inside it — and a record that may leave the process is the wrong place to discover what is in it for the first time. If you want the detail, catch it in the callback, where you know what you are looking at.
