Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

A JSON error causes the packaging to fail

Hello everybody,

When I try to make a cook in Win64 of the game. I have 3 errors like this that generate a "Failure".

This would be a JSON problem. In my project, JSON is only used to communicate with our remote database via HTTP requests.

UATHelper: Packaging (Windows (64-bit)): LogInit: Display: LogJson: Error: Json Value of type 'Object' used as a 'String'.

The data base returns me from the JSON that I deserialize.

The error can come from any request. So, the first time I saw the error, I disabled all queries. Without success. These requests have been present for more than 6 months and have not been modified since. This is the first time that there is an error related to the use of JSON in the project.

Have any of you ever encountered a similar problem or have research leads?

Thank you in advance for your help, which is precious to me. Good day to you :)

Okay. The bug is resolved for me. I have used a variable of type "Map" with Linear Color + Enumeration.

Accessing data in this variable generated a JSON error during the build. The bug has been fixed using a structure array instead of a map.

I hope i have help you if you see the same bug in your project.
