Description

IMPORTANT TO KNOW

CHANGES

• Adds handler for vendor overview with the route /me/{id}

TODO

I think need one more check in our VendorsAuthMiddleware that the Email of our vendor matches with the one on keycloak. If we won't implement it, I assume anyone can log into someone else's account, right @nanu-c ?

This should actually work like Adds handler for vendor overview with the route /me/ without an id. So i can only get my own data. The keycloak userinfo should include the email, that is then used for searching the vendor.

Okay there is some gap that I still do not understand about keycloak providing us specific information but if you say all I should is removing the /{id}/ part I will do this and merge it @nanu-c ?
