Why does the HAR strict failure have no code, hint or docs link like every other error?

✖ CONFIG_INVALID: Layer "api" is not enabled for project demo-shop (layers: ui).

Error: HAR strict mode: no recorded entry for POST https://jsonplaceholder.typicode.com/posts 0736c37d8e28 in /srv/ci/projects/demo-shop/har/staging/posts.api.har

  Not intentional, and not converted yet. Two different things are going on.

  The structured shape comes from the error class the CLI throws: it carries a code, an optional hint and an optional docs path, and the renderer prints them as the three lines you are parsing. Anything that is not one of those errors falls back to INTERNAL plus the message.

  The strict miss is a plain error thrown by the API replayer, and it is thrown inside the test worker rather than in the CLI, so it surfaces through the test reporter and never reaches that renderer at all. Even if it did, it has nothing to render.

  There is a HAR_MISS code sitting in the error enum that this throw site does not use, which tells you roughly what happened: the code was reserved and the throw was never moved over.

  So: real gap, not a design decision. In the meantime do not parse it as a coded error — it will not gain a code silently.

  For what it is worth, the message carries more than the coded ones do. It gives you the exact lookup key that missed and the exact file it looked in, which is everything you need to fix it. The coded errors give you a docs link.

  If your wrapper needs a stable marker, match on the literal prefix HAR strict mode: no recorded entry for — it comes from one place in the code, so it is at least not ambiguous.
