`StepFunctionGetExecutionOutputOperator` raises `JSONDecodeError` when `DescribeExecution` returns an ordinary error such as `States.TaskFailed`. AWS documents [`error` as a string](https://docs.aws.amazon.com/step-functions/latest/apireference/API_DescribeExecution.html#API_DescribeExecution_ResponseSyntax), whereas `output` contains JSON data. Return non-JSON errors unchanged, including empty strings. Preserve JSON-decoded error return values for compatibility and keep invalid success output and service exceptions visible. Document that fetching an error may complete the Airflow task successfully; checking remote execution success remains the responsibility of `StepFunctionExecutionSensor`. The documentation also explains the constraints on string results with `multiple_outputs` and dynamic task mapping. Validation on Python 3.10 in the official Linux/amd64 Breeze CI image: - Regression tests against the unchanged operator: 4 failed, 5 passed. With the fix, the related Step Functions operator, hook, sensor and trigger suite: 38 passed. - Regression tests use a real boto3 client and hook with botocore `Stubber`; a separate local synthetic HTTP-response experiment also exercised the botocore response parser. Neither contacts AWS. - Regular and manual prek checks passed, including provider mypy; commit-message checks and `git diff --check` passed. - Selective-check completed. The wider dependent-provider, Airflow-version, documentation-build and system-test matrices were not run locally. Actual AWS executions and full task-runner/XCom integration were not tested. --- ##### Was generative AI tooling used to co-author this PR? - [X] Yes — OpenAI Codex (GPT-6) Generated-by: OpenAI Codex (GPT-6) following [the guidelines](https://github.com/apache/airflow/blob/main/contributing-docs/05_pull_requests.rst#gen-ai-assisted-contributions) -- This is an automated message from the Apache Git Service.
