[Statefun] Exception occurs during function chaining / Async function

flint-stone
Hello!

I'm getting an exception running a modified version of datastream/statefun example. (See exception details that follow.) The example was adapted from the original datastream example provided in statefun repo. I was trying to play with the example by chaining two functions (with the 1st function simulating async IO function invocation). However I'm getting an exception saying that the mailbox is closed before the operation finishes. I'm adding the source code of the example here (Please ignore the printing statement and variable usage not making any sense since I'm debugging). The example works without chaining the second function or without using AsyncIO in any of the functions. Any ideas why this happens? Any suggestions would be appreciated.


Thanks!

Re: [Statefun] Exception occurs during function chaining / Async function

Seth Wiesman
Hi Le,

I believe the issue is the bounded source[1]. Stateful Functions only supports unbounded inputs.

Additionally, you can remove all the `synchronized` blocks from your code; statefun handles all synchronization for you.
