potiuk opened a new pull request, #66539:
URL: https://github.com/apache/airflow/pull/66539
## Summary
`scripts/ci/notify_uv_lock_conflicts.py` constructs the GitHub GraphQL
client as:
```python
self._http = httpx.Client(base_url=GRAPHQL_URL, ...)
...
r = self._http.post("", json=...)
```
`httpx` normalises `base_url` to end with `/`, so
`base_url="https://api.github.com/graphql"` plus a relative path of `""`
resolves to `https://api.github.com/graphql/` (trailing slash) — which GitHub's
GraphQL API rejects with `404 Not Found`. This breaks the `Notify uv.lock
conflicts` workflow on every main-branch push.
```
httpx.HTTPStatusError: Client error '404 Not Found' for url
'https://api.github.com/graphql/'
```
Failure:
https://github.com/apache/airflow/actions/runs/25492428820/job/74803563077
## Fix
Drop the `base_url=` kwarg and pass the full `GRAPHQL_URL` to `.post()`
directly so httpx never adds the trailing slash. Comment in the code records
why so the next person who is tempted to "clean it up" doesn't reintroduce the
bug.
