Crash when attempting to open 'Query Hydrus' menu

[RubyRed404]

Hatate repeatedly crashes when attempting to open the 'Query Hydrus' menu.
Immediately when I click on the menu point, hatate crashes into the ground.

Have tried installing older hatate versions.
Have tried re-installing hatate.
Have tried restarting both hatate and hydrus.
Have not yet tried generating a new/different api key for hatate.
Yes, I have made sure the api key is correct.
It works when sending hatate found/and tagged files to hydrus.

It is only this one menu item that does not work, and this would be really important for my uses, as I have a lot of files I want to tag and having to go trough and add every single one of the 256 folders hydrus makes is not only an inefficient use of time, but also a waste of resources, as I'm importing a lot of files which are already tagged

The following log has been translated by deepL, as for some unbeknownst reason, the logs were printed in my computers native language, which is not english.

Not sure if this is something that would help as I am a little out of my depth here but doing a quick search on the internet led me to this:
https://stackoverflow.com/questions/33495634/unable-to-cast-object-of-type-newtonsoft-json-linq-jobject-to-type-newtonsoft

Particularly this answer seems like a simple solution to the problem:

Hopefully this can help someone here...
(if there is still anyone here..)

Looks like at a glance that the Hydrus API has changed in a way that Hatate has not yet been updated to handle.

The technical details are simple: Hatate is trying to retrieve a list of what Hydrus calls services, like your "local files" service or "local files" service that house your data. It used to provide them directly in the query that Hatate is performing, but now it's provided as an array of children in the result. I get the same problem on ver538, though I'm not sure specifically when the API change happened.

I worked around it by updating the code on my copy on HydrusQuery.xaml.cs#146.

			foreach (var item in services) {
				string key = (string)item.Key;
-				JArray jArray = (JArray)item.Value;
+				IEnumerable<JObject> jArray = item.Value.Children<JObject>();

It might be more work for @nostrenz though if they want to support the older API scheme as well as the new one in the same build. I might submit a PR if I get the time and inclination to do so.

Hi! As you can see I was a little short on time to work on Hatate lastly.
I've published a new release implementing @terrehbyte's fix, and it should work for both the latest version of Hydrus as well as the older ones.

Sorry for the long wait, however I do appreciate those bug reports, so thanks for helping fixing/improving Hatate!
