Q	A
Bug report?	yes

In Pimcore 6 I'm getting a 500 error when a request is made to /lucene-search I'm following the "frontend implementation" guide as written in this repositry but it doesn't work.

When I check the logs I get the following error:

To be brutally honest I'm not 100% sure what I'm reading here.

@MustardOnPizza have you been able to solve this issue? I ran into the same problem :/

Edit: After some hours of debugging and testing I figured out it was related to a Pimcore issue. Disabling/enabling the plugin solved the issue.

I ended up writing my own search from scratch hahaha
