Null inside socket.data object's field
yarikpetrenko opened this issue · comments
I have middleware that sets socket.data and one of this object properties can be null. When socket.io-admin-ui in development mode it runs registerVerboseListeners
function. Which laters calls createProxy
function on "connection" event for every filed inside socket.data. Inside createProxy
there is a check:
if (typeof obj !== "object") { return obj; }
but typeof null is also "object" so it will pass and will try to init new Proxy with null as target - new Proxy(null, ...)
which will throw an error - "TypeError: Cannot create proxy with a non-object as target or handler" or similar.
In my case it also crash whole app when this error occur.
