Logstash Management user with default logstash_admin rol prevents logstash from starting

[searchtool]

Hi,

i noticed when using the out of the box role logstash admin for a user as described in the docs

xpack.management.elasticsearch.username and xpack.management.elasticsearch.password
If your Elasticsearch cluster is protected with basic authentication, these settings provide the username and password that the Logstash instance uses to authenticate for accessing the configuration data. The username you specify here should have the logstash_admin role, which provides access to .logstash-* indices for managing configurations.

Logstash will not start due to an failing bootstrapcheck.

I found out that when i use a superuser account for management the xpack license check completes ok.

is there more to it ? or did i fail somewhere

elastic, logstash 7.0.1
