Per the [doc](https://www.elastic.co/guide/en/elasticsearch/reference/8.1/api-conventions.html#api-date-math-index-names), I'm trying to create an index with the date in it's name: ```auto PUT /%3Call-dns-%7Bnow%2Fd%7D%-0000013E?pretty { "aliases": { "all-dns": { "is_write_index": true } } } ``` But I'm getting this error: > { > "error" : "Incorrect HTTP method for uri [/%3Call-dns-%7Bnow/d%7D%25-0000013E?pretty=&pretty=true] and method [PUT], allowed: [POST]", > "status" : 405 > } > Changing the method to POST is no better: ```auto { "error" : "no handler found for uri [/%3Call-dns-%7Bnow/d%7D%25-0000013E?pretty=&pretty=true] and method [POST]" } ``` This used to work, because I just changed the name in prior commands devtools. ---

Think you are missing the last `%` before the `3E` `PUT /%3Call-dns-%7Bnow%2Fd%7D-000001%3E?pretty` ---

Still not working, I don't know if I lost the % posting or what, but re-testing: ![image](https://us1.discourse-cdn.com/elastic/original/3X/e/9/e949f01dbfd81c2865004c6b2c8b6b2c6496d7b2.png) ---

@rugenl Screen shot BAH! please post the actual text so I can try! Mine on 8.2.0 (should be same in 8.1.3) ```auto PUT /%3Call-dns-%7Bnow%2Fd%7D-000001%3E?pretty { "aliases": { "all-dns": { "is_write_index": true } } } ``` response ```auto { "acknowledged" : true, "shards_acknowledged" : true, "index" : "all-dns-2022.05.19-000001" } ``` Something weird in your url... ![Screen Shot 2022-05-19 at 11.47.31 AM](https://us1.discourse-cdn.com/elastic/original/3X/d/6/d6ab89dcf40cd93a28a200b41bdf20585365ee41.png) When I purposely use wrong method my url prints this... note no `/` where yours is `"error" : "Incorrect HTTP method for uri [/%3Call-dns-%7Bnow%2Fd%7D-000001%3E?pretty=&pretty=true]` ---

Stay tuned, same syntax that fails in 8.1.3 works in 7.17.1. I knew we used this many times before and was pretty sure I started with an example that had worked in the past. ---

@rugenl Interesting I reproduced the error in 8.1.3 ```auto PUT /%3Call-dns-%7Bnow%2Fd%7D-000001%3E?pretty { "aliases": { "all-dns": { "is_write_index": true } } } ``` results ```auto { "error" : "Incorrect HTTP method for uri [/%3Call-dns-%7Bnow/d%7D-000001%3E?pretty=&pretty=true] and method [PUT], allowed: [POST]", "status" : 405 } ``` Note it has that extra `/` in it in 8.2.0 It works fine.. so looks like there is a bug in 8.1.3 that is fixed in 8.2.0 You can certainly create manually with the following syntax or upgrade to 8.2.0 ```auto PUT all-dns-2022.05.19-000001?pretty { "aliases": { "all-dns": { "is_write_index": true } } } ``` ---

That format is a ILM red herring, all indices will have 2022.05.19, not the current date at rollover. ---

Using the date math {now/d} will put the current date at rollover in the index name at each rollover event. If you use a literal date for the first index, that date will be used in all future indices. ---

If you use a literal date for the first index, that date will be used in all future indices. Hmmm I will need to validate for myself as I was not aware of that / not my understanding ... unfortunately to validate I need to wait for a UTC date rollover to trigger the date portion in 20 hours (pretty sure I have manually bootstrapped many indices with the literal... but perhaps I am wrong or something has changed) either way now I have to know 🙂 Thanks for pointing out. ---

It burned me early in ILM, it's been awhile, it's possible it's fixed, but I think it needs the {date/d} in the "provided\_name" field in the index to know a date isn't a constant. ---

@rugenl Yes You Are Correct you must use the `{now/d}` syntax... So for anyone reading this your date driven rollover must be defined with the correct syntax In Kibana -\> Dev Tools you can use the non encoded syntax (in some versions) ```auto PUT /?pretty { "aliases": { "my-index-write-alias": { "is_write_index": true } } } ``` If you are posting through a REST endpoint you will need to encode ```auto PUT /%3Cmy-index-%7Bnow%2Fd%7D-000001%3E?pretty { "aliases": { "my-index-write-alias": { "is_write_index": true } } } ``` BTW @rugenl I realized I was thinking of the non date form with the of the beats aliases ```auto PUT /filebeat-7.17.3-000001/?pretty { "aliases": { "filebeat-7.17.3: { "is_write_index": true } } } ``` ---
