After upgrading Graylog from v2.4.7 to v3.3.5 I get the error below in every dashboard widget and search box
“Unable to perform search query: failed to parse date field [2020-09-03 16:50:49.121] with format [strict_date_optional_time||epoch_millis].”
Clearly I have missed something in the upgrade docs! Any help hunting down this problem will be greatly appreciated.
Elasticsearch v6.8.12
Mongod v3.6.19
I’m not sure if it will solve your issue but you might try rotating the index/indices against which your widgets and searches querying. Are you using any custom index mappings?
