i'm getting 500 errors submitting posts to strapi because this extension seems to be choking on the unique id field

I'm getting the exact same error when I have clearRelatedCache: true (I also have a uid field in my model)

If i disable clearRelatedCache everything is fine.

Hey @selfagency and @jpizzle34

I've had a look at the code, it does seem to be an issue in version 1 of the middleware. That said the code has been completely reworked in the v2 (beta branch). Upgrading to it might solve this issue for you

npm install --save strapi-middleware-cache@2.0.1-beta.2

(note, configuration format has evolved a bit since and might require some changes when you do upgrade)
