This is just so other people had same problem.
Error

**[esaggs] > Cannot read property 'doc_count' of undefined **

After upgrade from any version to 7.3.1 your visulize will break if you have use filter
because by default it uses lucene
you now have to use KQL

only solution so far I have found is to change all the viz and change from Lucene to KQL

I thought that this issue was fixed in 7.3.1- there's a pull request for this error with a discussion including workarounds: https://github.com/elastic/kibana/issues/43188

Looks like it is not fixed for sure.

Yesterday evening I upgraded 7.2.0 to 7.3.1 and got this error.
