Expecting : /%3Cfoo-%7Bnow%2FM%7Byyyy.MM%7D%7D%3E/_doc

but : /%253Cfoo-%257Bnow%252FM%257Byyyy.MM%257D%257D%253E/_doc

elasticsearch error log
reason=Invalid index name [%3Cfoo-%7Bnow%2FM%7Byyyy.MM%7D%7D%3E], must be lowercase]

"<foo-{now/M{yyyy.MM}}>" is not a valid index name. The index name must be either a lowercases String or a SpEL (Spring Expression language) template expression. What do you want to achieve with the String you provide?

Check https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-create-index.html#indices-create-api-path-params for what characters are allowd in an index name.

i want Date math support in index names

Ok; didn't know that. I will need to investigate this and to try to reproduce it.

[sothawo]

ok, I can reproduce that. That reactive client escapes the '%' with '%25'. This does not happen in the non-reactive part.
