• Fork this code sandbox or another minimal reproduction.

I try to get the type of model by using Instance method just like the doc recommended, but the result confused me:

when i define a model like the pic below, it works fine

but when i define a model in this way, i got a unknown type

Is there anyway i can avoid this or i just missed some key information when reading the doc?

@JLUiceman are you on the latest version? I wasn't able to reproduce :(

type resolution does not work for me in WebStorm

although it works in vs code

@thegedge Thanks for reply! Yes, project's current mst version is 6.0.1;
@kuguarpwnz kuguarpwnz's comment inspired me; I tried to run the same code in VSCode, and it works fine :). I'm curious why there is such a difference.

Great question!

If I had to guess, it's one of three things:

1. A language server other than tsserver that's behaving differently.
2. The language server not properly loading up tsconfig.
3. Wrong version of typescript is evaluating things inside the language server.

That being said, I'll flag this as a perhaps a small docs update where we could have a callout for issues with types when using WebStorm. If you do figure out what the issue is, though, drop a comment here :)

Yep, I will also continue to follow up on this issue and try to find out the possible reasons. If there are further conclusions, I will comment here.
Thanks for your patient explanation, and hope we can got a solution:)
