I create ILM/Template and Index when I try to write via python it errors but same record works via dev tool ```auto POST sachin_test/_doc { "@timestamp": "2024-06-06T19:21:15.000Z", --> this part I did manually "system_type": "gpu", "available": 1, "maintenance_status": 1, "cpu_core_inventory": 0, "sum_cpu_core_inventory": 0, "sum_gpu_card_inventory": 0, "count": 1, "system_prod": "yes", "center": "hou", "host_status": "maintenance" } ``` Here is python record looks like `{'@timestamp': Timestamp('2024-06-06 13:45:00+0000', tz='UTC'), 'system_type': 'gpu', 'available':1, 'maintenance_status': 1, 'cpu_core_inventory': 0, 'sum_cpu_core_inventory': 0, 'sum_gpu_card_inventory': 0, 'count': 1, 'system_prod': 'yes', 'center': 'hou', 'host_status': 'maintenance', '_index': 'sachin_test', '_op_type': 'create'}` it says error is 500 document(s) failed to index. An exception of type BulkIndexError occurred. Arguments: ('500 document(s) failed to index.',) ---

> [@elasticforme](#): > > {'@timestamp': Timestamp('2024-06-06 13:45:00+0000', tz='UTC'), Hmmm You should probaly share your python code. Did you simply try ` 'timestamp': datetime.now(),` Like the Example here to see if it works... ---

Basically I do push this using helpers.bulk ```auto mylist = [{'@timestamp': Timestamp('2024-06-06 13:45:00+0000', tz='UTC'), 'system_type': 'gpu', 'available':1, 'maintenance_status': 1, 'cpu_core_inventory': 0, 'sum_cpu_core_inventory': 0, 'sum_gpu_card_inventory': 0, 'count': 1, 'system_prod': 'yes', 'center': 'hou', 'host_status': 'maintenance', '_index': 'sachin_test', '_op_type': 'create'}] helpers.bulk(elastic_output, mylist) ``` ---

Delete the index first and then try doing the python first. Perhaps there's something wrong with the initial doc you posted ---

if I write to different index all togather ( regular index) then it works. something with TSDS and timestamp for sure. ---

Did you walk through this carefully? > **[Set up a time series data stream (TSDS) | Elasticsearch Guide \[8.14\] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/set-up-tsds.html)** ---

ok it works. Thanks @stephenb basically I had time different between TSDS creation and @timestamp that I was inserting. ---

I think when you create TSDS with index.mode = time\_series enable then it has two value index.time\_series.start\_time value set to `now - index.look_ahead_time` index.time\_series.end\_time value set to `now + index.look_ahead_time` and you can only write between these two time.
