MessageHandler | Simple Handler forwarding | Learning library

Since your client has read 499 messages, we know that some messages were published by the producer. Have you verified that there were in fact more than 499 messages in the queue? That can be done using the RabbitMQ web manager. A nice feature of steam queues is that messages can remain in the queue after consumers have read them.

If the rest of the messages were published, then it is likely that the consumer closed its connection before all messages were consumed. The example from the blog (repo here) uses the Utils.waitAtMost method to delay closing the connection:

"message" is not even a key(check statement 4)

It is, but Object.keys is designed to list enumerable properties, and message is not enumerable.

In the ECMAScript specification, we see in the section on the Error constructor that the constructor creates its message (and other properties) with the procedure:

Perform CreateNonEnumerableDataPropertyOrThrow(O, "message", msg).

Other -- custom -- properties can of course be added to Error objects by JavaScript code, which explains why other properties are listed by Object.keys().

As to the output of console.log: the console API implementation has a lot of freedom on how to display objects -- lot's of differences can be found between implementations.

To also output those non-enumerable properties, use

For some reason this seems to be an error that happens with some frequency, so I rather post an answer instead of a comment.

You are supposed to add message classes to the routing configuration, not handler classes.

Your configuration should be, if you want that message to be manages asynchronously:

I use this pattern for CMake shaders that works with both Ninja and the MSVC generators.

You only have 1 thread running the IO service. Everything is on an implicit strand (Why do I need strand per connection when using boost::asio?), no need to worry UNTIL you start using a new thread.

The simplest fix, then, would seem to make sure sending the replies happens on the IO service as well:

Update object, inside of the message field, has the from field which is a User Telegram object containing the user's ID.

Once you have the user's ID, you can use the sendMessage method in order to reply him easily.

To conclude, instead of:

$set will replace a new value for the key. If you use the 3rd value then the $set will replace the 3rd value, use $push instead of $set operator.https://docs.mongodb.com/manual/reference/operator/update/push/

WatchQueue does get called on each OnAfterRenderAsync; we ignore firstRender

This looks like Apple's defect, because updateUIView is called, but evaluateJavaScript (internal JavaScript) generates exception, because bridge.onMessage is lost and not a function more.

Here is found work-around - reset WebView on scene activation (app comes into foreground), as it recreated with current states the previous values are preserved. Tested with Xcode 13.2 / iOS 15.2
