What is Nest-Keycloak-Connect, you ask?
Nest-Keycloak-Connect is a fantastic library that allows you to integrate Keycloak, a popular identity and access management solution, with your Nest.js application. It provides a seamless way to authenticate and authorize users, making it a go-to choice for many developers.

is the base URL, and myrealm
is the realm name.

The most common reason for the “Realm URL is missing the first part of the URL” error is a misconfigured Keycloak setup. Don’t worry, it’s an easy mistake to make!
Here are the common culprits:
- Incorrectly formatted realm URL in the
keycloak.json

baseUrl
configuration in thekeycloak.json
file - Invalid or missing

Frequently Asked Question
Are you stuck with the nest-keycloak-connect realmUrl issue? Don’t worry, we’ve got you covered! Here are some frequently asked questions and answers to help you resolve the problem.
Q1: What is the realmUrl and why is it important in nest-keycloak-connect?
The realmUrl is a crucial configuration option in nest-keycloak-connect that specifies the URL of the Keycloak realm. It’s essential because it tells Keycloak where to redirect users for authentication and authorization. Without a valid realmUrl, your application won’t be able to communicate with Keycloak, and you’ll encounter errors.

The first part of the realmUrl might be missing due to a incorrect configuration or a typo in your environment variables. To fix this, double-check your Keycloak realm URL and ensure it starts with the correct protocol (http:// or https://) followed by the domain name and realm path. For example, https://example.com/auth/realms/myrealm
. Update your environment variables or configuration files with the correct realmUrl, and restart your application.

No, you cannot use a relative URL for the realmUrl in nest-keycloak-connect. Keycloak requires a fully qualified URL that includes the protocol, domain name, and realm path. Using a relative URL will result in errors, so make sure to provide an absolute URL that starts with http://
or https://
.

To troubleshoot the realmUrl issue, start by checking your Keycloak server logs for any errors or warnings related to the realmUrl.
