Process.env.react_app_api_key undefined

Explanation:

The error message “process.env.react_app_api_key undefined” indicates that the environment variable “react_app_api_key” is not defined.

In a React application, you might be using environment variables to store sensitive information like API keys or other configuration values. These variables need to be defined in the environment where the application is running.

To fix this error, you need to make sure that the “react_app_api_key” environment variable is defined and accessible in your application.

Here’s an example of how you can define an environment variable in a React application:

REACT_APP_API_KEY=your_api_key

Note the “REACT_APP_” prefix in the variable name. This is required for Create React App applications to recognize the variable.

After defining the environment variable, you can access it in your React application using:

const apiKey = process.env.REACT_APP_API_KEY;

Make sure to restart your application after defining the environment variable to apply the changes.
