Is 'transaction' reserved?

[YuanhengZ]

I am following: https://docs.litestar.dev/2/tutorials/sqlalchemy/1-provide-session-with-di.html
Where I defined something like:

@get("/sqlite")
async def get_list(transaction:AsyncSession) -> RecordCollection | dict[str, str]:
    logger.info("Access to get_list route detected.")

    results = [serialize_record(todo) for todo in await get_all_records(transaction)]
    if not results:
        return {"success": "No records found."}
    return results

app = Litestar(route_handlers=[index, upload_file, log_file, get_list],
               logging_config=logging_config,
               lifespan=[db_connection],
               dependencies={"transaction":provide_transaction}
               )

This runs fine, however, if I rename "transaction" into something like "active_session" the program fails.
So is transaction reserved for litestar?

transaction is defined as a dependency (dependencies={"transaction":provide_transaction}). It will be injected under the key it's defined at. If you want to use a different key, you'll have to rename it in the dependency declaration as well as the function where it's being used.
