feat: return structured import errors by TheTisiboth · Pull Request #3538 · nextcloud/cookbook

TheTisiboth · 2026-10-29T20:35:27Z

Addresses #3279

Depends on #3510 (stacked).

Topic and Scope

Gives users a clear reason when an import fails.

All import errors return a JSON Error object instead of a plain string; failures at a given step add step (download, parse_html, extract_recipe), missing recipe name included
Unexpected errors return 400 with a generic message (details only in the log)
Error responses no longer leak file/line (import, create, update)
Frontend shows msg for all 4xx import errors
API spec (trunk) and API changelog updated

Concerns/issues

API change: clients parsing the plain-string 400 body of the import endpoint need to read msg. Other endpoints still return plain-string errors; to be migrated in a follow-up PR.

Formal requirements

I did check that the app can still be opened and does not throw any browser logs
I created tests for newly added PHP code (check this if no PHP changes were made)
I updated the OpenAPI specs and added an entry to the API changelog (check if API was not modified)
I notified the matrix channel if I introduced an API change

AI disclosure

I used AI for code gen.

Import failures return {msg, step}, unexpected errors a generic 500, and error responses no longer leak file/line. Frontend and API docs follow the new format.

Walkthrough

Import errors now use structured responses with a msg field and, for import-step failures, a step field. Recipe extraction exceptions are tagged with extract_recipe. Unexpected import and caching errors return generic messages. The API documentation and client alert handling reflect the response format.

Merge Risk: Minimal · up to 70d62

Import errors use structured messages. A malformed page can still produce a 500 instead of the documented response, but this narrow pre-existing failure does not block merging.

Full details: Docstring Coverage

Explanation

Docstring coverage is 66.67% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 6 functions across 4 files. (2 skipped: 2 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

There are a few fixed, I would like to incorporate before we can merge this.

christianlupus · 2026-11-04T17:42:02Z

 				'url' => UrlRedactionHelper::redact($data['url']), 'step' => $e->getStep(), 'reason' => $e->getMessage(), 'exception' => $e,
 			]);
-			return new JSONResponse($e->getMessage(), 400);
+			return new JSONResponse(['msg' => $e->getMessage(), 'step' => $e->getStep()], Http::STATUS_BAD_REQUEST);


We should not use status codes 5xx in custom code. These imply server failure and unexpected behavior. Also, this will trigger the bad message The server reported an error. Please check. (in AppNavi.vue) which should be avoided if possible.

Also in case of a non-expected error, there will be a 500 with a dummy HTML page that will not be parsable as JSON at all.

This is especially true, as the ImportException is a rather common exception here (e.g. due to download errors or parser issues.

yeah my bad, we should only return 400, i completely agree 👌

 ## Unpublished

+### Structured import errors


This is a breaking change of the API., we have to keep that in mind.

If we do this step, we might consider merging #3453 as well.

how should we manifest this breaking change in the changelog?

christianlupus · 2026-11-04T17:55:33Z

+                    typeof data === 'string'
+                        ? data
+                        : (data.msg ?? t('cookbook', 'Import failed.'));


This simplifies the logging to some extend. However, as we already consider a breaking change on the API, it migt be a good opportunity to migrate all errors to report a real JSON object in favor of plain strings. Then, the null problem would be gone as well.

I simplified it now 😇
