Hi Langium, I implemented validation error for undefined variable.
But how to not be showing the validation error for undefined variable once user created the variable?
Currently, the error msg will only be updated after the LSP restarted.

Hi, what exactly did you implement. Usually this works ootb.

I found the issue. I did a caching for types, so the type is not the same as in the backend.
