Search in Magento products error: Invalid filter type

I am using Magento 2.2 and a custom theme. When using the frontend search, I am getting the following exception (URL e.g. /catalogsearch/result/?q=Tshirt)

1 exception(s):
Exception #0 (InvalidArgumentException): Invalid filter type

I could not find any information on this error.

Answer 1

I finally found the solution (for me) on github (https://github.com/Smile-SA/elasticsuite/issues/1114)

I had to resave the product attribute "Visibility" and clear the cache afterwards. That did the trick!

Answer 2

There was a problem with the custom attribute created. Had to delete the attribute and create again. Worked for me!
