Hello, i've tried to deploy the elk-stack 7.1.1 but kibana does not starts and throws an exeption. ```auto FATAL AssertionError [ERR_ASSERTION]: New route /plugins/de.dimdi.util.monitoring.elk:dimdi-elk:jar:7.1.1-SNAPSHOT/{path*} conflicts with existing /plugins/de.dimdi.util.monitoring.elk:dimdi-elk:jar:7.1.1-SNAPSHOT/{path*} ``` And this is the content of the kibana log file. ```auto {"type":"log","@timestamp":"2019-05-31T08:27:25Z","tags":["fatal","root"],"pid":20753,"message":"{ AssertionError [ERR_ASSERTION]: New route /plugins/de.dimdi.util.monitoring.e lk:dimdi-elk:jar:7.1.1-SNAPSHOT/{path*} conflicts with existing /plugins/de.dimdi.util.monitoring.elk:dimdi-elk:jar:7.1.1-SNAPSHOT/{path*}\n at new AssertionError (internal/ assert.js:269:11)\n at Object.exports.assert (/home/nana/elk/kibana-7.1.1-linux-x86_64/node_modules/hoek/lib/index.js:736:11)\n at module.exports.internals.Segment.intern als.Segment.add (/home/nana/elk/kibana-7.1.1-linux-x86_64/node_modules/call/lib/segment.js:67:14)\n at module.exports.internals.Segment.internals.Segment.add (/home/nana/elk /kibana-7.1.1-linux-x86_64/node_modules/call/lib/segment.js:61:40)\n at module.exports.internals.Segment.internals.Segment.add (/home/nana/elk/kibana-7.1.1-linux-x86_64/node _modules/call/lib/segment.js:61:40)\n at exports.Router.internals.Router.internals.Router.add (/home/nana/elk/kibana-7.1.1-linux-x86_64/node_modules/call/lib/index.js:63:26) \n at internals.Server._addRoute (/home/nana/elk/kibana-7.1.1-linux-x86_64/node_modules/hapi/lib/server.js:467:46)\n at internals.Server.route (/home/nana/elk/kibana-7.1. 1-linux-x86_64/node_modules/hapi/lib/server.js:456:22)\n at internals.Server.exposeStaticDir (/home/nana/elk/kibana-7.1.1-linux-x86_64/src/legacy/server/http/index.js:62:10) \n at Object.register (/home/nana/elk/kibana-7.1.1-linux-x86_64/src/legacy/server/plugins/lib/plugin.js:62:16)\n at internals.Server.register (/home/nana/elk/kibana-7.1.1 -linux-x86_64/node_modules/hapi/lib/server.js:431:35)\n at Plugin.init (/home/nana/elk/kibana-7.1.1-linux-x86_64/src/legacy/server/plugins/lib/plugin.js:75:28)\n at Plugi n.init (/home/nana/elk/kibana-7.1.1-linux-x86_64/node_modules/lodash/index.js:7407:25)\n at callPluginHook (/home/nana/elk/kibana-7.1.1-linux-x86_64/src/legacy/server/plugin s/lib/call_plugin_hook.js:37:25)\n generatedMessage: false,\n name: 'AssertionError [ERR_ASSERTION]',\n code: 'ERR_ASSERTION',\n actual: false,\n expected: true,\n operat or: '==' }"} ``` i have the elk-stack 5.1.1 that runs with the same configuration. no authentication, no x-pack. only the standard configuration.

Hi Nana, have you installed some custom plugins inside of `src/plugins`? If so, is it possible that you have more than one plugin installed with the same `id`? This is a bit of a guess, but the code which throws the error you noted does a check of all plugins when they initialize, so it seems the most likely culprit. ---

Hi cjcenizal, i have not installed any custom plugins. i have only unzipped the files and set my configurations. i run the elk-stack 5.1.1 with the same configuration. here is my kibana configuration : server.port: {kibana.http.port} server.host: "{kibana.host}" server.name: "{kibana.host}" elasticsearch.hosts: ["http://{elasticsearch.host}:{elasticsearch.http.port}"] logging.dest: "{env.vars.elk.home}/kibana.out" logging.quiet: true thank you for your reply.

Hi Nana, unfortunately I can't reproduce your error. Could you try using a new download, fresh install, with the default settings and see if that fixes your problem? If so, can you try introducing your custom settings one by one until you identify which one causes the error you're seeing? ---
