Elastic search indexing fails with: Failed to recreate index

Bitbucket fails to create index on elastic search. We're using elastic search 7.1.1.

We're aware that atlassian does not recommend elastic search above 6.5.3, but we have a hard limit on our elastic search version of 7.0. 

We see that Bitbucket starts and then fails with

Hey @steven qent 

There are quite a few documented breaking changes In Elasticsearch 7 (https://www.elastic.co/guide/en/elasticsearch/reference/current/breaking-changes-7.0.html#breaking_70_indices_changes) that may be to blame (assuming you’ve validated all your permissions are correct). 

If anyone else has managed to get BB working with ES7, would be interested to know.

Thank you Craig. I'm certain that between ES6 and ES7 the index isn't compatible. Which is why we're trying to recreate the entire index. We have no permission related issues. 

Was there any resolution to this issue? Having the exact same error show up for Bitbucket 6.9.1 and ElasticSearch 7.5.1

Hi @Chris lerner 

6.9 doesn’t show as a supported ES version yet either. I’ve lodged a premier support ticket to see when newer ES version support will land. Will update when I hear back.
