Gracefully ignore the recipe image if used in graph mode

[hdkirschbaum]

Nextcloud version:
32.0.3.2

Cookbook version:
0.11.8

Recipe URL:
https://www.chefkoch.de/rezepte/1192990086557/Paprikanudeln.html

Problem:
Since today, importing Chefkoch recipes fails.
The recipe file is created, but no recipe data is imported.

Log output:

libxml: Fehler 68:
htmlParseEntityRef: no name

libxml: Fehler 23:
htmlParseEntityRef: expecting ';'

libxml: Fehler 801:
Tag amp-bind-macro invalid

libxml: Fehler 76:
Unexpected end tag : svg

The same Chefkoch URLs worked yesterday.
curl downloads the page successfully.
The page contains valid schema.org JSON-LD recipe data.

Browser: works correctly
curl: works correctly
Only Cookbook import fails

I just tried that recipe. It seemed to fail. Okay, on debug mode, I tried again and the recipe was already downloaded. It was simply not shown (and yeah, that errors should not have happened). Could you check in the files app if an appropriate folder was generated? Eventually, you can enfore reloading the recieps from disk in the settings.

related to the image I see a separate issue. Let's look at this one piece at a time. First please verify that at least the recipe seems to be downloaded in general. Thanks!

The recipe folder contains a valid recipe.json; also the other files.

I can open "import.html" and "recipe.json", but there are no pictures in "full.jpg" and "thumb.jpg"

Now i can see the recipe in the android app, but there are no pictures.

I have the same problem since yesterday. Just after I updated the app, not sure how it was before.

Within the before faild receip trying to change the picture to an other one on my instance works sometimes but not always. If it works, thums are also only generated sometimes.

I checked the import data from said site (which will probably affect all Chefkoch pages). This comes from a known limitation of this app: the schema.org (which we use for importing) is based on a graph. In the past these graphs were typically of very simple structure and it was not necessary to have a full blown graph parser on board. This is a known limitation #1675 and possibly more. With the latest changes of the Chefkoch page, we are no longer able to parser it completely.

We should though avoid the error message here in any case to disturb the users as little as possible.
