TL;DR

EDIT: DO NOT DO THIS IN PRODUCTION. Doing so creates a large security flaw. I have created my own realm apart from master.

The error, verbatim

Context: Stack Overflow #45352880 (top answer, 128 votes, 33 answers): I am trying to hit an endpoint from my API to authenticate a user from Keycloak, but it's giving me error Invalid parameter: redirect_uri on the Keycloak page. I have created my own realm apart from master. Keycloak is running on HTTP.

Fix
