The function refreshConnectionsStream is not handling any potential errors that might occur during the execution of getConnectionsStream. This could lead to unhandled exceptions or silent failures, making it difficult to debug and maintain the code.

To improve this, you should add an error event listener to the stream returned by getConnectionsStream. In the error event handler, you can emit an event on the eventBus to notify other parts of your application that an error has occurred. This way, you can handle the error gracefully and provide feedback to the user or log the error for debugging purposes.

The function getConnections is not handling any potential errors that might occur during the execution of the getMiners function. If createAxios or the subsequent call to /miners fails for any reason (e.g., network issues, server error, etc.), it will throw an error that is not being caught. This could lead to unexpected behavior or crashes in your application. To improve error handling, you should wrap the contents of getConnections in a try-catch block and handle any errors appropriately, such as logging the error and returning a default value or rethrowing the error to be handled by the caller.

The function getConnectionsStream is using a global variable interval to store the interval ID from setInterval. This could potentially lead to issues if this function is called multiple times, as it would overwrite the previous interval ID, making it impossible to clear the previous interval. This could lead to memory leaks and unexpected behavior. To avoid this, you should consider storing the interval ID in a closure or in an object that is tied to the lifecycle of the relevant component.

Also, the function disconnect is called without being defined or imported anywhere in the provided code. If it's not defined elsewhere in the codebase, this will result in a ReferenceError at runtime. Make sure that disconnect is properly defined and available in this scope.
