aws-error-utils
Error-handling functions for boto3/botocore
Decision gist · record as of 2026-08-14
Yes. The package is lightweight (pure Python, one dependency), production-stable, carries no security vulnerabilities, and meaningfully reduces error-handling boilerplate. Dormant maintenance is not a concern because error handling for existing AWS services rarely changes. Install it if you write botocore code with more than a few try-except blocks.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Low friction: pure Python wheel with only botocore as a runtime dependency.
- Maintenance is dormant (last release 2022-11-03, no commits since 2023-11-11), but the package is marked Production/Stable and has no known vulnerabilities, suggesting it is feature-complete rather than abandoned.

What it is and what it does
aws-error-utils simplifies exception handling for botocore by converting opaque ClientError objects into Pythonic exception classes and named tuples. When botocore raises a ClientError, all error details are buried in nested dictionaries (e.g., error.response['Error']['Code'], error.response['Error']['Message']); this package exposes them as direct attributes (error.code, error.message, error.http_status_code, error.operation_name) and lets you catch specific AWS error codes as exception types (e.g., except errors.NoSuchBucket) rather than inspecting dictionary contents.
The package provides three main interfaces: the `errors` class for simple error-code matching in except blocks, the `catch_aws_error()` function for more complex conditions (including regex matching or operation-name filtering), and the `get_aws_error_info()` function to extract error metadata from any ClientError. It requires only botocore as a dependency and supports Python 3.7 through 3.11.
Use it for
- Catch specific error codes like NoSuchBucket or NoSuchKey without parsing nested dictionaries in except blocks.
- Match errors by both error code and operation name when multiple API calls exist in a single try block.
- Extract HTTP status codes and error messages from ClientError for logging or custom error reporting.
- Use regex or custom callables to match errors based on message content rather than just error codes.
- Reduce boilerplate in exception handling code that calls multiple AWS services.
