Could you provide your kcl code？Or do you have this problem on all kcl codes?

[pisarenko91]

Hey, it is everywhere. But I think I narrowed down the issue to, if I initiate IntelliJ instance with idea . I get those errors. But if I use absolute path idea User/foo/bar I dont get the pop ups.

Also it would be awesome if it would show me suggestions on . , for example if I do things like some_array. it will give me suggestions and available methods. I dont get that at the moment. Thanks a lot for doing this.

I checked the relevant code and it seems that some deprecated features are causing the error. These codes will be removed in the next version.
