# libtmux.exc.ObjectDoesNotExist

- **Module:** libtmux.exc
- **Package:** libtmux
- **Language:** Python
- **Kind:** exception
- **Source:** https://github.com/tmux-python/libtmux/blob/036c521c4b83ce6e434eb50afe2a0d08a6a05e46/src/libtmux/exc.py#L154

A lookup expected one object and matched none.

Raised by :meth:`~libtmux._internal.query_list.QueryList.get` when nothing
matches and no ``default`` was passed.

## Example

```python
>>> from libtmux import exc
>>> str(exc.ObjectDoesNotExist())
'No objects found'
```

## Example

A lookup that named what it wanted says so:

```python
>>> str(exc.ObjectDoesNotExist(query={"pane_id": "%99"}))
"No objects found: pane_id='%99'"
```

## Example

It is part of the :exc:`LibTmuxException` hierarchy, so ``except LibTmuxException`` catches it:

```python
>>> issubclass(exc.ObjectDoesNotExist, exc.LibTmuxException)
True
```
