centos yum upgrade for elastic to 7.11 breaks kibana
Closed this issue · 1 comments
Dear,
For the rocknsm installed from the rocknsm 2.5 iso upgrading to lastest elasticsearch breaks kibana
Many errors are shown for** [esaggs] > Unexpected token < in JSON at position 0**
It is impossible to diagnose what went wrong or is going wrong
Possible root causes remain unclear: one assumed is a permission issue or a deprecated feature
FINALLY found something tangible
When ‘Inspect’ ‘View:Requests’ ‘Response’ all Error fields are found to be generated because of
{
“message”: “Unexpected token < in JSON at position 0”,
“code”: “STREAM”
}
solved by downgrade to Kibana 7.10 then deleting index .kibana_3 and .kibana_2 as suggested in the log, then stop/start kibana
could not get around request to delete .kibana_1, after deleting this dashboards were gone
Performed install procedure as document in the rock-dashboards readme and restored the dashboards succesfully.
