Kibana error after upgrade to version 8.0 from 7.17.0 [No validation schema has been defined for [xpack.canvas]

Elastic Stack Kibana
1

Hi,

I have updated my elasticstack from version 7.17 to 8.0 recenly. All of my 3 Elasticsearch nodes and 2 logstash nodes are working fine. But whenever I am trying to upgrade to Kibana version 8.0 it is thowing below error.

{"ecs":{"version":"8.0.0"},"@timestamp":"2022-02-27T17:27:39.815+06:00","message":"No validation schema has been defined for [xpack.canvas]","error":{"message":"No validation schema has been defined for [xpack.canvas]","type":"Error","stack_trace":"Error: No validation schema has been defined for [xpack.canvas]\n at ConfigService.isEnabledAtPath (/usr/share/kibana/node_modules/@kbn/config/target_node/config_service.js:166:13)\n at PluginsService.handleDiscoveredPlugins (/usr/share/kibana/src/core/server/plugins/plugins_service.js:203:25)\n at PluginsService.discover (/usr/share/kibana/src/core/server/plugins/plugins_service.js:66:5)\n at Server.preboot (/usr/share/kibana/src/core/server/server.js:155:30)\n at Root.preboot (/usr/share/kibana/src/core/server/root/index.js:48:14)\n at bootstrap (/usr/share/kibana/src/core/server/bootstrap.js:99:9)\n at Command. (/usr/share/kibana/src/cli/serve/serve.js:216:5)"},"log":{"level":"FATAL","logger":"root"},"process":{"pid":5738}}

Can anyone please help me understand what should be the way forward to mitigate this error? Thanks in advance.

Anyone facing the same problem?

You need to remove xpack.canvas from kibana.yml file. Probably you disabled it some time ago. Only a few plugins can be disabled starting from v8.0

Thank you for your reply. So I have hashed these lines which I am not using. Below is my xpack configuration.

#xpack.monitoring.enabled: true
#xpack.graph.enabled: false
#xpack.ml.enabled: false
xpack.security.enabled: true
#xpack.watcher.enabled: false
xpack.reporting.enabled: true
xpack.spaces.enabled: true
#xpack.canvas.enabled: true
xpack.encryptedSavedObjects.encryptionKey: VALUE
xpack.reporting.encryptionKey: VALUE
xpack.security.encryptionKey: VALUE
xpack:
monitoring:
enabled: true
min_interval_seconds: 10
monitoring.kibana.collection.enabled: false

But now below error is occurring. I am using SSL and TLS in elasticsearch, but not in Kibana. So is this the issue here?

Hi Mikhail_Shustov,

Can you please check my previous comment and let me know what am I doing wrong?

My error is "message":"[config validation of [xpack.security].enabled]: definition for this key is missing"

As xpack.security is mandatory what to do to remediate this?

Solved this by disabling xpack.security.enabled, xpack.reporting.enabled & xpack.spaces.enabled. As mentioned in document these setting are causing the problem.
