The GraphQL for Unity Asset uses the Newtonsoft version which is built in newer version of Unity (2020+). If you get an error like this:
Assembly 'Library/ScriptAssemblies/Assembly-CSharp.dll' will not be loaded due to errors: Reference has errors 'GraphQL'. Assembly 'Assets/GraphQL/Libs/GraphQL.dll' will not be loaded due to errors: GraphQL references strong named Newtonsoft.Json Assembly references: 22.214.171.124 Found in project: 126.96.36.199. Assembly Version Validation can be disabled in Player Settings "Assembly Version Validation"
- Then you can try to remove NewtonSoft dependency from your project – if you have a dependency. And just use the NewtonSoft version which is already built in and shipped with Unity 2020+. If you use an older version of Unity then you can try to copy the NewtonSoft DLL from 2020 and use this in your older Unity version.
- Or you can go to Project Settings -> Player -> Other Settings and deactivate “Assembly Version Validation”
- Install the newtonsoft package from Unity. Go into the package manager and click “+” and then select “Add package from git URL” and fill in “com.unity.nuget.newtonsoft-json”.
