"Unexpected attribute syntax_type on node of type scope" in stderr

We’re seeing a lot of these messages in standard-error:

Unexpected attribute syntax_type on node of type scope

These are emitted here, and stem from the fact that "syntax_type" is not included in SCOPE_ATTRS:

stack-graphs/tree-sitter-stack-graphs/src/lib.rs

Lines 431 to 432 in 7b15ca4

    
           static SCOPE_ATTRS: Lazy<HashSet<&'static str>> = 
        
               Lazy::new(|| HashSet::from([TYPE_ATTR, IS_EXPORTED_ATTR, IS_ENDPOINT_ATTR]));

I’m not sure whether "syntax_type" should be in SCOPE_ATTRS, or the attribute is erroneously added to scope nodes in TSGs — seems to me it’s the former, but I’ll leave that up to you.

Thanks for the report! For which language are you getting these errors? And is this using a released version or the repo's main branch?

In principle, setting syntax_type in scope nodes doesn't make much sense, but we also allow source_node on all nodes it seems, which is kind of similar.

Not sure about the source language — this came from an internal report so I’ll try to chase that down. I’m pretty sure it’s one of the languages in this repo (Java/JS/Py/TS). It’s tree-sitter-stack-graphs 0.8.1

The github/stack-graphs repository is no longer being maintained. As per #502, I'm closing all issues and pull requests before archiving the repository.
