Why
---
`LLMFileAnalysisOperator` do not support `.md` file and return
`LLMFileAnalysisUnsupportedFormatError`.
What
---
- add `md` in `SUPPORTED_FILE_FORMATS`
- update `LLMFileAnalysisOperator` docs
Test
---
Use the testing dag with self host LLM.
```python
from pathlib import Path
from airflow.providers.common.ai.operators.llm_file_analysis import
LLMFileAnalysisOperator
from airflow.providers.common.compat.sdk import dag, task
MARKDOWN_PATH = "/tmp/llm_file_analysis_repro.md"
@dag(
dag_id="repro_llm_file_analysis_markdown",
schedule=None,
catchup=False,
tags=["manual", "repro", "common-ai"],
)
def repro_llm_file_analysis_markdown():
@task
def create_markdown_file() -> str:
Path(MARKDOWN_PATH).write_text(
"# Incident report\n\nThe API returned HTTP 503 for five
minutes.\n",
encoding="utf-8",
)
return MARKDOWN_PATH
markdown_path = create_markdown_file()
LLMFileAnalysisOperator(
task_id="analyze_markdown",
prompt="Summarize the incident report.",
llm_conn_id="pydanticai_default",
file_path=markdown_path,
)
repro_llm_file_analysis_markdown()
