BettyBossi is not working

[Danit2]

Pre-filing checks

• [x] I have searched for open issues that report the same problem
• [x] I have checked that the bug affects the latest version of the library

The URL of the recipe(s) that are not being scraped correctly

• Kokos-Schokolade-Würfel

The results you expect to see

I use "Mealie" on Home Assistant and there the Betty Bossi Website is not working. In the repositories from Mealie they say this is a problem from the recipe-scrapers

The results (including any Python error messages) that you are seeing

I become a error message from Mealie.

Hi @Danit2 - thank you for the bugreport, we should be able to investgate this soon.

There are two details that would be helpful to narrow this down, if available:

• Does mealie indicate the verson of recipe-scrapers that is in use? (I would guess it will look something like v14.50.1 or similar)
• Are there any details in the error message? (such as Failed to retrieve recipe title or similar)

Thanks!

Hi @jayaddison

Thanks for your answer.

My version of Mealie use the recipe-scrapers version 14.55.0

On the Logs i don't see anything. I'am Sorry.

Extremely helpful, thank you @Danit2 - I hope to investigate this within the next day or so.

Ok, this is an interesting bug. I think what is happening here is that:

• Mealie requests the recipe page from BettyBossi.
• BettyBossi responds to some/all requests with a tiny HTML page containing a JavaScript snippet that redirects to the recipe (this can be an effective bandwidth/bot-reduction technique).
• Mealie receives the minimal redirect page as HTML, but the HTTP client it uses (httpx) - like many/most Python HTTP clients - does not evaluate the JavaScript code, so the tiny HTML (with no recipe content) is returned.
• recipe-scrapers received the tiny HTML page and doesn't find the recipe information in there.

My guess is that if a user-agent followed the redirect to get to the recipe URL, and downloaded the HTML from that second page, then recipe-scrapers would be able to extract the recipe metadata.

I'll have to spend a bit of time to think about this. It could be good to double-check this theory, too, if anyone out there has time to help.

I would be willing to help solving the problem with Betty Bossi, though I am not a developer.

[jayaddison]

@Zwirbel1 if you have time, then if you could check whether any open source recipe management / import utilities are able to handle BettyBossi could be useful info for this, to get an idea for whether the same problem has been solved elsewhere (and perhaps how).

[Zwirbel1]

I have tested it last week with Tandoor, which was able to import a recipe from Betty Bossy in the demo version online: https://docs.tandoor.dev/. Here's the menu I have imported into the demo version of Tandoor: https://app.tandoor.dev/view/recipe/53071.

It seems like bettybossi.ch uses anti-scraping techniques and as mentioned already in this issue (https://github.com/hhursev/recipe-scrapers/issues/531) you need to reload the page 2 times in order to get the correct HTML.

[Zwirbel1]

@SwissOS : I tried reloading the page various times, but I get the same URL and HTML, which does not allow me to import the recipe. Anything else I can change to get the correct HTML / URL?
