”Unknown answer return from server, see log”

[faxotherapy]

Description I imported receipe from Marmiton. Now, when I want to edit it, I got the following error message: “unknown answer return from server, see log”.

[index] Error: Exception: OCA\Cookbook\Service\ThumbnailService::createThumbnail(): Return value must be of type string, null returned in file '/var/snap/nextcloud/38457/nextcloud/extra-apps/cookbook/lib/Service/ThumbnailService.php' line 82 at <<closure>>

PUT /index.php/apps/cookbook/webapp/recipes/9344

I allso get the following error message:

[PHP] Error: Undefined array key "id" at /var/snap/nextcloud/38457/nextcloud/extra-apps/cookbook/lib/Helper/Filter/JSON/RecipeIdTypeFilter.php#15

Reproduction Steps to reproduce the behavior:

1. Import recipe from Marmiton
2. Save and exit.
3. Come back to the recipe.
4. Edit it
5. Then, save.

Expected behavior After saving, the app should say “Saved”

Actual behavior Only one pop-up window saying “Unknown answer return from server, see log”

Browser Thorium

Versions Nextcloud server version: 27.1.3 Cookbook version: 0.10.2 Database system: MySQL

Hi, I did a new test, using Firefox and no problem at all. I was using Chromium-based Thorium browser. Initially I did not think that a browser could affect the behavior of a web app. Clearly, Thorium affects how Cookbook behaves. You can, for example, manually create a new receipe, add a few instructions, then SAVE, and notice that the last one of the instruction set is never saved. Using Thorium browser, this happens consistently. Maybe Thorium is a bit too much optimised… Falling back on Firefox, no issue. I added some more recipes with Firefox and everything is OK.

I have the same problem except it happend when I try to save a new recipe, that I created manualy in the web interface. I also use the Firefox browser.
