<dynamic remote listing>

Error message

<dynamic remote listing>

What it means

Not a failure: printRemotes formats the remote listing ('origin', optionally with verbose URL lines) and delivers it via a thrown CommandResult, matching the app's output-as-exception convention.

Solutions

1. Catch CommandResult and render e.msg
2. Use the command dispatcher so output is handled for you

Example fix

// before
engine.printRemotes({}); // throws
// after
try { engine.printRemotes({}); }
catch (e) { if (e instanceof CommandResult) display(e.msg); else throw e; }

function isCommandResult(e){ return e instanceof CommandResult; }

try { engine.printRemotes(options); } catch (e) { if (e instanceof CommandResult) { show(e.msg); } else { throw e; } }

When it happens

Trigger: Running `git remote` or `git remote -v` successfully; direct calls to printRemotes(options).

Common situations: Programmatic use of GitEngine without catching CommandResult; expecting a return value instead of a throw.
