There was a failure at the management server, such as a database access error. The user has no permission for the certificate template or the certificate authority is unreachable. MREGISTER_E_DEVICE_CERTIFCATEREQUEST_ERROR Windows 8.1: This constant is not available before Windows 10. Invalid Schema, Message Format Error from server. The datatype does not match the expected datatype. To learn more, read Live events.The following error values are with MDM registration. When you're ready to test your integration, use the Live events page to get a real-time view of your feature flag requests as they're received. Next stepsĪfter you have set up an SDK, you can manage features on your flags list. To learn more about how SDKs handle streaming connections, read Receiving updates from LaunchDarkly.Īll SDKs provide synchronous and asynchronous ways of waiting for the SDK's state to initialize. When an SDK loses connectivity to LaunchDarkly, it continues to try to reestablish a streaming connection until it succeeds. SDKs may periodically drop streaming connections. You can specify the fallback value in your flag evaluation code. If you evaluate a flag before the SDK receives its initial state, or you try to fetch a flag which otherwise doesn't exist, then the SDK returns a fallback value. If you make a change in the flags list or with the REST API, LaunchDarkly sends these changes to all connected SDKs automatically. After the initial update, the SDK keeps a streaming connection open to LaunchDarkly. The response from LaunchDarkly contains the SDK's current state, which your SDK uses to make any necessary changes to feature flags. When the SDK first initializes, it opens a streaming connection to LaunchDarkly. No network communication is required when you evaluate a flag.īy default, an SDK initializes with an empty state. The SDK relies on its stored state to evaluate flags. If the SDK you use loses the connection with LaunchDarkly, your feature flags will still work. If your team uses aliases to find all flag usage throughout your codebase, you will also have hover documentation wherever those aliases appear. These integrations have extended functionality based on Code References aliases. LaunchDarkly offers further integrations for VSCode or IntelliJ IDEA. SDK documentation appears in your editor if the editor supports surfacing doc comments. You need to shut down the application manually only one time. If your application quits without this shutdown step, requests and the Contexts list may not be populated, because they are derived from analytics events. The client releases the resources it is using and sends pending analytics events to LaunchDarkly, if any. Shut down the LaunchDarkly client when your application is about to terminate.Contexts that exist in your SDK appear in the Contexts list automatically after they encounter feature flags. After you create contexts in your SDK, you can target them with feature flags before they appear on your Contexts list. You don't have to send contexts to LaunchDarkly in advance. Use the key to associate flag variations with different contexts. Every feature flag is uniquely identified by a feature flag key. Set which feature flag variation a context will receive.Your SDK key, client-side ID, and mobile key uniquely identify your project and environment, and they authorize your application to connect to LaunchDarkly. Configure the LaunchDarkly client with the appropriate key for your environment and create the client.This client is the primary way your application uses the SDK and communicates with LaunchDarkly. Import the LaunchDarkly client in your application code.This lets your application access the LaunchDarkly SDK. Install the LaunchDarkly SDK in your application using your project's dependency manager.We auto-generate SDK API documentation each SDK, which is linked from each SDK's reference page. We provide reference documentation for all SDKs under SDKs. To learn more about choosing an SDK, read Client-side and server-side SDKs. We provide a variety of server-side, client-side, mobile, and edge SDKs to choose from. The steps to integrate your application with LaunchDarkly are similar across all SDKs. This topic explains how to set up an SDK to begin using LaunchDarkly. Read time: 4 minutes Last edited: Jul 17, 2023
