The error message sounds a bit like in this issue:

> [@What is excluded column in kibana index pattern?](https://discuss.elastic.co/t/what-is-excluded-column-in-kibana-index-pattern/252667/10):

> Steps to reproduce: Create index pattern from filebeat-7.9.2 index (doesn't matter if I designate @timestamp as time-filter or not) Wait about 5 minutes (index pattern will work during this time and not have source filter present or @timestamp field marked as excluded) View index pattern in Discover tab, receive following error: [error1] FieldParamType/\_this.deserialize@https://some.url.com/33984/bundles/plugin/data/data.plugin.js:9:345453 setParams/\<@https://some.url.com/33984/bundles/plu…

So there is an issue with your index pattern, I think you're refreshed the fields in the index pattern management? Which version of Winlogbeat are you using?

Thx & Best,
