I have a new install of Strapi, have connected it to my MySQL db and was able to create a new collection type (tests). However, when trying to do a GET request, I receive a 404 error message

GET Request: localhost:1337/tests

Strapi Response: {“data”:null,“error”:{“status”:404,“name”:“NotFoundError”,“message”:“Not Found”,“details”:{}}}

Obviously I can find “tests” in the Strapi Admin - that’s where I created it - and it’s also accessable via phpMyAdmin - but I can’t retrieve data anymore.

I had a Strapi 3.x version previously and it all worked fine, but when I nuked that and went to the current version, it doesn’t work anymore.

Can anyone tell me what I’m doing wrong?
