Methods

__init__

• __init__(*, snapshot_kvs_name): None

• Parameters

  • optionalkeyword-onlysnapshot_kvs_name: str | None = None

  Returns None

capture_snapshot

• async capture_snapshot(error_message, file_and_line, context): None

• Capture error snapshot and save it to key value store.

  It saves the error snapshot directly to a key value store. It can't use context.get_key_value_store because it returns KeyValueStoreChangeRecords which is committed to the key value store only if the RequestHandler returned without an exception. ErrorSnapshotter is on the contrary active only when RequestHandler fails with an exception.

    Used in filename of the snapshot.
