Unable to get query

Error message

Unable to get query

What it means

Same stdin protocol as [22]: the `var_stdin` preview reads `<selection><EOF><query><EOF><variable>` from stdin. The second `parts.next()` is the query; if the payload lacks a second field the `expect` panics with "Unable to get query".

Solutions

1. Confirm the finder preview command passes the QUERY placeholder in the correct position (second field, before the EOF delimiter)
2. Update the finder config template to match this CLI's expected `<selection><EOF><query><EOF><variable>` format
3. Test by piping a full three-field payload into the preview command manually
4. Replace the `expect` with `ok_or_else` + `?` for a graceful error

Example fix

// before
let query = parts.next().expect("Unable to get query").to_owned();
// after
let query = parts.next().ok_or_else(|| anyhow!("Unable to get query from stdin payload"))?.to_owned();

let fields: Vec<&str> = text.split(EOF).collect();
if fields.len() < 2 || fields[1].is_empty() {
    eprintln!("stdin payload missing query field");
}

fn has_query(text: &str) -> bool {
    text.split(EOF).nth(1).map_or(false, |q| !q.is_empty())
}

let query = text.split(EOF).nth(1)
    .ok_or_else(|| anyhow!("no query in stdin payload"))?;
// validate payload shape before parsing rather than catching panics

When it happens

Trigger: The stdin payload contained a selection but no query segment — i.e. only one field before EOF, or the stream ended after the first field.

Common situations: Finder preview template not updated to pass the QUERY placeholder; older/newer finder emitting a different number of fields; hand-crafted preview invocation missing the query.
