Forbidden by ReadonlyREST ES plugin with "Add policy to index template" action in Kibana

Hello,

When I try to add a new IML policy to an existing index template i get the following error:

Even if it was well allowed by the ES plugin there was an exception in the log:

Have you any idea of what is happening ?

Thanks a lot.

Hugues

Thanks for reporting this issue. I’ve added it to our backlog. I will let you know here when it’s fixed

Thanks a lot.

I’m better organized now and will be able to test a pre-release version if it would be helpful for you.
