Import Failed Exception: on some recipe imports

[krisgesling]

Hey, first wanted to say thanks for the awesome app, absolutely loving it so far!

Issue description

When importing some recipes using the Android app, I'm seeing the following error displayed as a red bar at the bottom of the screen:

Import Failed Exception: type 'Null' is not a subtype of type 'String' in type cast

Without re-importing - navigating to the list of recipes shows that the initial import was successful.

I do not get this error if using the import function through the NextCloud Cookbook web interface eg https://exampledomain.com/apps/cookbook/#/

Example recipe:

• https://www.taste.com.au/recipes/slow-roasted-capsicums-filled-mushroom-feta/e413060d-6aee-47f4-adbe-d0e5b8223f60

Additional details

• Google Pixel 7
• App from Play store - last updated 25 March 2023 (v0.7.9 according to the changelog)
• Nextcloud v25.0.3
• Cookbook app v0.10.2

This should already be fixed on the develop branch but unfortunately a few restructures prevent a new release at the moment.

I'll add unit tests to make sure this can't happen again and hope that a new release is ready in one to two weeks.

Ok never mind I can't reproduce this behavior on the master branch so far. further information is welcome :)

Hmm, no repro = likely something in my setup then...

Some other urls that returned the same error:

• https://www.easypeasyfoodie.com/mexican-roasted-sweet-potato-cubes/#recipe
• https://www.thespruceeats.com/mexican-spice-mix-recipe-1809302#
• https://cookieandkate.com/vegetarian-enchiladas-recipe/

Here's the error and preceding warnings from the NextCloud server logs for the capsicum recipe - IP and user have been redacted. Each of the urls above returned the same error, with slightly different libxml warnings as you'd expect. My assumption is that these warnings are expected and not related to the real issue but I'm including them for completeness.

Same for me. I've only imported from https://chefkoch.de for now but it's the same for every recipe.
