Question about how to parse JSON
Hello, i am trying parse simple JSON string for test, i place node "Make literal string" with value:
{"test":"valueTest"}
This string will come from outsource, unrelated with this plugin
Then i try parse it many ways, but everytime get empty
First it decoding it and print, second it encoding to string and print, third it placing object to structure, break struct and print string - any of this way don't work, also if i try write [] (square parentheses) and parse it like array!
After trying to print everything in log, i get that after converting from value to object, json string is become empty.
But if i trying to create json from this plugin - it works!
I print initial (literal) string and this thing above, they are same!
I not undestand, same strings but 1 don't parsing and 2 parsing perfectly!
Outsource is not NodeJS server or something, is just string from UDP

There the problem is that the array was received. But in my case i received not array!
As i already said, i try to get my string in array like:
[{"test":"valueTest"}]
And get elements
But this won't work. Value is get empty after converting to Object
Print after "To JsonValue (String)" - exist, print after "To Object (JsonValue)" - empty
#296
Sorun şu ki, dizi alındı. Ama benim durumumda dizi almadım! Daha önce de söylediğim gibi, dizimi şu şekilde diziye almaya çalışıyorum: [{"test":"valueTest"}] Ve öğeleri alıyorum Ama bu işe yaramayacak. Değer "To JsonValue (String)"den sonra Object Print'e dönüştürüldükten sonra boş oluyor - var, "To Object (JsonValue)" sonrasında yazdır - boş
Json value(string) AS Array > For each loop > as object > get string field {fieldname:test} > print string
download Varest plugin for more features use it with the plugin it works very well

I don't use Rest server
UE4.26 - latest for him socketio is 1.6.0, but in plugin UDP that i use from same developer, where is socketio included - 1.5.5, i don't see in 1.6.0 changelog some changes for my problem
And i already done that you wrote
To parse a raw json string from e.g. some other source use ValueFromJsonString(UObject* WorldContextObject, const FString& StringValue); (https://github.com/getnamo/socketio-client-ue4/blob/9765f50ffc5b0a4cde6486c8538cc72befe5c425/Source/SIOJson/Public/SIOJsonValue.h#L110)
Using to json value will wrap the string value as an json value type, not decode the string as you're expecting.
For the other way (siojsonvalue to string) you want to use Encode json node (https://github.com/getnamo/socketio-client-ue4/blob/9765f50ffc5b0a4cde6486c8538cc72befe5c425/Source/SIOJson/Public/SIOJsonValue.h#L160)
I get this plugin because i not understand programming and hope to do my work in blueprints, but if i need to work with code, i have to switch to another plugin(
These are blueprint callable functions, same name as c++, drag off node and type the name out
