# Check if an object does not exist — Amazon S3

Botize method — `aws_s3.object_non_exists` (action).

Check whether an object does not exist in an Amazon S3 bucket.

This is an action: it runs as a step of a task. Several can be chained.

## Fields you set

The field's internal name, its type and the values it accepts. These fields accept `{{...}}` tags from earlier steps.

- `bucket` *(string)* — Bucket
- `name` *(string)* — Look for the existence of this object

## Output variables

Data this step makes available. Reference them in later steps with the double-brace tag.

- `{{object_exists}}` *(text)* — Object Exist
