System.InvalidOperationException: stack is empty

[Zaitonn]

net version:4.7.2
jint version: 3.0.0 beta 2044 (latest by now)
os: win10

I added a specific CLR type reference to the engine like this

engine.SetValue("WebSocket", TypeReference.CreateTypeReference(engine, typeof(JSWebSocket)));
// https://github.com/Zaitonn/Serein/blob/c094e5e74d72ef65bcded9970a6b1de562344a0f/Serein/Universal/Plugin/JSEngine.cs#L129-L130

// JSWebSocket is my wrapper for another class
// https://github.com/Zaitonn/Serein/blob/main/Serein/Universal/Plugin/JSWebSocket.cs

and I used it in js codes like this

var ws = new WebSocket(config.addr);

i used it to connect to my ws server and it worked for a while
but then what made me confused was that it gave me a exception

System.Reflection.TargetInvocationException: 调用的目标发生了异常。 ---> System.InvalidOperationException: stack is empty

I cannot call his methods and properties any more
I think that there is no problem in the class WebSocket. is the instance cleared by the gc?

and there is another problem...

sometimes it gave me diffierent exception

is it my problem? :(

waiting for your reply❤thanks

Are you accessing the engine from multiple threads? Engine is not thread-safe.

[Zaitonn]

do you mean that i should lock the engine when executing codes?

[lahma]

Depends on the answer to my question.
