Error message

query {file_name} is not supported by Zed and should be removed

What it means

Raised during `extension test languages` when a file inside a language directory parses successfully as a QueryFile (e.g. highlights.scm, injections.scm) but the language's grammar failed to resolve or load, so Zed cannot compile the query. The with_context call augments the underlying grammar-loading error to state that language {name} declares query {path} without a usable tree-sitter grammar.

Solutions

1. Verify the language entry in extension.toml declares a valid `grammar` field pointing to a tree-sitter grammar that clones and builds successfully
2. Check that the grammar repository, path and revisions in the grammar declaration are correct and reachable
3. Run the language tests locally with the extension CLI to confirm the grammar compiles before publishing
