Fix SerovalMissingPluginError

in Clerk

Solution

The "SerovalMissingPluginError" in Clerk typically arises when the serialization library (Seroval) used by Clerk lacks a plugin to handle specific data types present in your application's Clerk data, such as custom objects in public or private metadata. To fix this, identify the problematic data type and install the corresponding Seroval plugin, for example, use `npm install seroval-plugins-arraybuffer` if encountering ArrayBuffer errors and register it with `registerSerovalPlugins([ArrayBufferPlugin])` during your application's initialization. Ensure the plugins are installed on both server and client if server-side rendering is involved.
