[500 Internal] unexpected closed request stream while trying to write a message

[imrefazekas]

Dear Team,

Please find the attached ESM code.
A simple workflow "WF" wants to send a "fire and forget" message to a non-existing service.

The call does not produce an error at all, but
in the console of the workflow asynchronously (meaning if you add more logic to the workflow after that call, that following code lines start to be executed like nothing happened) :

"Got abort error from connection: The operation was aborted."
And in the web page of restate:

[500 Internal] unexpected closed request stream while trying to write a message

There is no error thrown in the code so try-catch does not help, no code-level tool to able to react to it.

Please find attached screenshots ...

System: macOS 26.3 (25D125)
Same results with bun 1.3.9, node 24 and node 22.

Restate can run in docker or locally, same result.

Thanks!

docker-compose.yml
Emty.js

The error above is I would call a rare case, most of the time its

...because of a failed precondition: the service handler Nonexisting/process was not found

as intended ....
