Specify the environment variables available to the working instance

The environment variables used by the default Worker instance are isolated from the environment variables in the system to prevent pollution and control the reading range. If there are environment variables in the system that need to be accessed by the Worker instance, you can set a whitelist.

The SDK provides the setPlatformEnvironmentVariables method for setting the whitelist:

await agent.setPlatformEnvironmentVariables([
    {
        key: 'NODE_ENV',
        value: 'production'
    }
]);
