Description

many stub exceptions are producing an equivalent stack trace:

Error during processing of: AttributeDetails__Story.re

I think that it comes from the fact that PsiInclude or PsiOpen are trying to resolve a path and store it in a stub.
from idea forum:

Some causes we've seen include:

leaf/composite PSI mismatch (thanks Vladimir for pointing that out!)
LightStubBuilder not working in the same way as the normal one would (by building stubs by AST)
errors in incremental parsing (e.g. IReparseableElementType#isParsable incorrectly returning true on broken code, when full reparse would produce a different result)
asymmetric stub serialization/deserialization code
lexer/parser/AST/PSI/stubs depending on something more than the file's content: other file, project settings, etc

Maybe the last point is the culprit.
Need to remove the stub for path. it’ll be computed each time and not cached anymore.
problem is that the indexing is used in the resolver ! :(
