elasticsearch.helpers.BulkIndexError: 1 document(s) failed to index

[pulse-mind]

Hello,

I'm having this error

File "/Users/pulsemind/.virtualenvs/vdatac/lib/python3.10/site-packages/elasticsearch/helpers/actions.py", line 521, in bulk
    for ok, item in streaming_bulk(
  File "/Users/pulsemind/.virtualenvs/vdatac/lib/python3.10/site-packages/elasticsearch/helpers/actions.py", line 436, in streaming_bulk

    yield from gen
  File "/Users/pulsemind/.virtualenvs/vvdatac/lib/python3.10/site-packages/elasticsearch/helpers/actions.py", line 274, in _process_bulk_chunk_success
    raise BulkIndexError(f"{len(errors)} document(s) failed to index.", errors)
elasticsearch.helpers.BulkIndexError: 1 document(s) failed to index.

when running
python manage.py search\_index --rebuild

I had some difficulties to know which Document is having a problem ? why ? ... ?

Nothing in the logs : /opt/homebrew/var/log/elasticsearch/elasticsearch...

(I am new with elastic search)

Actually I changed the source code locally to do :

 if errors:
     raise BulkIndexError(f"{len(errors)} document(s) failed to index: {errors}", errors)

which is not nice if there are a lot of errors but in my case it helps me to understand what's going on.

If I look at the command, the rebuild is called like this:

    def handle(self, *args, **options):
        if not options['action']:
            raise CommandError(
                "No action specified. Must be one of"
                " '--create','--populate', '--delete' or '--rebuild' ."
            )

        action = options['action']
        models = self._get_models(options['models'])

        # We need to know if and which aliases exist to mitigate naming
        # conflicts with indices, therefore this is needed regardless
        # of using the '--use-alias' arg.
        aliases = []
        for index in self.es_conn.indices.get_alias().values():
            aliases += index['aliases'].keys()

        if action == 'create':
            self._create(models, aliases, options)
        elif action == 'populate':
            self._populate(models, options)
        elif action == 'delete':
            self._delete(models, aliases, options)
        elif action == 'rebuild':
            self._rebuild(models, aliases, options)
        else:
            raise CommandError(
                "Invalid action. Must be one of"
                " '--create','--populate', '--delete' or '--rebuild' ."
            )

So there is no way to get the errors here.
It would be good to add something like I did (with a better formatting) ?
