is not a table in workspace dependencies

Error message

{} is not a table in workspace dependencies

What it means

Thrown by `update_dependency_version_in_doc` (tooling/xtask/src/tasks/gpui.rs:257) when a [workspace.dependencies] entry parsed via toml_edit is not a TOML table (e.g. it's a bare string or inline value). The function only knows how to rewrite table-shaped dependency entries (setting version/package keys), so it bails rather than corrupting the manifest. Called by update_workspace_dependency_version and the unit test test_update_dependency_version_in_toml.

Solutions

1. Rewrite the offending [workspace.dependencies] entry as a table: `name = { version = "x.y.z", ... }`.
2. Run `cargo check`/`cargo metadata` to confirm the manifest parses, then re-run the publish xtask.
3. Inspect the entry near the reported package_name for missing braces or a flattened value.

Example fix

# before
[workspace.dependencies]
anyhow = "1.0"

# after
[workspace.dependencies]
anyhow = { version = "1.0" }

let doc: toml::Table = toml::from_str(&std::fs::read_to_string("Cargo.toml")?)?;
for (k, v) in doc["workspace"]["dependencies"].as_table().unwrap() {
    assert!(v.is_table(), "workspace dependency '{}' is not a table", k);
}

When it happens

Trigger: A [workspace.dependencies] key is written as a bare version string (e.g. `serde = "1.0"`) or any non-table value instead of a table/inline table (`serde = { version = "1.0", workspace = true }`), and the publish task attempts to update its version.

Common situations: Hand-edited Cargo.toml entries that dropped the `{ ... }` braces; dependencies on registry crates pinned as plain strings; automated formatting or merge conflicts that flattened inline tables.
