[Feature] Collect all errors raised by `--warn-error-options '{"error": ["NoNodeForYamlKey"]}'`

[kverburg]

Is this a new bug in dbt-core?

• I believe this is a new bug in dbt-core
• I have searched the existing issues, and I could not find an existing issue for this bug

Current Behavior

We got NoNodeForYamlKey warnings, so I wanted to make sure these get raised as errors and can't be merge as CI will block it.

But when I promote those with --warn-error-options, it just raises one error and does not display all. This would result in fixing one, running again and the next error would pop up.

Expected Behavior

I would expect this option to raise all the messages I previously got as warnings, to be raises an errors.

Steps To Reproduce

1. Add a YML with some non existing models
2. Run dbt compile --show-all-deprecations --no-partial-parse to see all the warnings
3. Run dbt compile --show-all-deprecations --no-partial-parse --warn-error-options '{"error": ["NoNodeForYamlKey"]}' and see that there is just one

Hi @kverburg

Raised a PR #12564 with the fix — catch EventCompilationError per iteration in PatchParser.parse() so the loop processes all patches before raising a combined error.

Thanks for opening this @kverburg ! And to @kalluripradeep for opening a pull request -- nice 1-2 combo 🤩

The current behavior looks expected to me, so converting from a bug to a feature request.

This sounds similar to the --show-all-deprecations flag (docs). We should consider whether we want to change the default, or just provide an optional flag to show all errors.

Hey @graciegoheen, yep indeed, as described in the issue I use that flag as "input" to get all the occurrences, but basically want it them all as errors.
