EntryPointNotFoundException with Unity 2017.1.1f1 (64bit), .NET 4.6 on Windows

[Bunkerbewohner]

Hi! I was excited to discover that Mixpanel offers a Unity plugin so I quickly integrated it by downloading the .unitypackage from github (v1.1.0) and I really like the API! However, when I start the game in the editor I get the following error at the beginning:

EntryPointNotFoundException: CSharp_mixpanelfdetail_new_Mixpanel__SWIG_2___
mixpanel.detail.Mixpanel..ctor (System.String token, System.String distinct_id, System.String storage_directory, System.Boolean enable_log_queue) (at Assets/Mixpanel/detail/Mixpanel.cs:53)
mixpanel.Mixpanel.Awake () (at Assets/Mixpanel/Mixpanel.cs:575)

Every call to Mixpanel.Track etc. causes a similar error and naturally no events are sent.

Unity Version: 2017.1.1f1 (64bit)
Scripting Backend: Mono
Scripting Runtime: .NET 4.6
Platform: Windows 10 Pro, Version 1703

Hi @Bunkerbewohner - could you try the previous release and see if it works for you?

Hi!

This somewhat works. I'm still testing, but I can already say for sure that some tracking calls work, such as:

Mixpanel.Track("EventName");
Mixpanel.Track("EventName", new Value() { ["value"] = 1234 });

However, calls like this crash the runtime:

Mixpanel.Track("EventName", 1234);
Mixpanel.Track("EventName", new Value(1234));
Mixpanel.Track("EventName", "Example");
Mixpanel.Track("EventName", new Value("Example"));

But I can make do with the verbose syntax. I will continue testing and see if the other stuff like timed tracking work. Thanks!

Thanks for the update @Bunkerbewohner ! Notice that you need to pass a JSON object to the properties (see https://github.com/mixpanel/mixpanel-unity/blob/master/deployments/UnityMixpanel/Assets/Mixpanel/Mixpanel.cs#L219)
It was not clear to me if you are now using the previous version or you are on the latest :) Want to make sure that 1.1.0 works fine!

Thanks for the tip about the JSON object! Maybe an error message instead crashing the application would have been clearer. ;-)

As for the version I am actually on the previous version 1.0.1 now! The latest version 1.1.0 still has the EntryPointNotFoundException problem for me.

Hello! I am getting the same EntryPointNotFoundException issue for the older version 1.0.1 as well.

I am using Unity 2017.3.1 and I have tried it on both, a Mac and Windows 10 system. Mixpanel v1.1.1 throws this error only on my Windows device, but v1.0.1 shows the same error for both Mac and Windows.

Could anyone tell me how to fix this problem?

Hi, I am getting the EntryPointNotFoundException on Windows with v1.1.1 version. Downgrade fixed it for Win, but break it for Mac. Any solution that works on both platforms with same version of Mixpanel?

Sorry guys, we have released a new version v1.2.0 with a fix to this problem, please try again and feel free to reopen it if the same problem still exists.
