How do you get the git commit hash from a run when queried from a repository?

Basically as the title says: How do you get the git commit hash from a run when queried from a repository?

I know that I can store the git commit via

run = Run(
      repo = path_to_repo,
      experiment = "experiment_name",
      log_system_params = True
)

and I can see the Git Info Card in the web interface.

However, when I try to query the git commit via the SDK:

repo = Repo(path_to_repo)
tag = "success"
# Run a basic query
query = f'"{tag}" in run.tags"
runs = [item.run for item in repo.query_runs(query, report_mode=0).iter_runs()]
for run in tqdm.tqdm(runs, desc=f"Extracting runs"):
    commit = run.__system_params.git_info.commit
    # more code

then I get the error AttributeError: 'Run' object has no attribute '__system_params'. Again, the same query from the webui works just fine. I debugged through the Run object a little bit, but could not find any meaningful fields / members.

For reference, I am using aim 3.23.0:

aim                3.23.0
aim-ui             3.23.0
aimrecords         0.0.7
aimrocks           0.5.2

Hey @sbuschjaeger! Thanks for the question.
This behavior is expected, as the dot-based syntax is only available in the context of queries, as part of the query expression.
Instead, the following syntax should be used:

commit = run['__system_params', 'git_info', 'commit']

Ah okay. Thanks for the clarification!
