Error when running NodeJS in Standalone mode, main script connection error #53

Closed mightyt73 closed 1 year ago

mightyt73 commented 1 year ago

Hello! I have been running into an issue trying to run this code in standalone mode in Unreal Engine. I am able to get the code working well in the Editor, but when running my application in Standalone the scripts do not seem to work. Is there anything I should look out for when trying to start the nodejs server in Standalone mode? or any suggestions on what I can look at to troubleshoot the issue.

Thanks!

Actually might be non-issue. I tested with the editor closed, on just a packaged product and seemed to work. So maybe its something conflicting when I run standalone with editor open. I will investigate there. Packaged product did work for me.

There are likely edge cases, I still consider this plugin an experimental one without robustness/stability expected out of something solid.

Yup I definitely understand. It has been very useful in my project.

The only issue I run into is that the plugin seems to hang at times and prevents my scripts for working. If I go into task manager and kill the nodejs subprocesses, it is then recreated and works fine again.

Any chance you know a way to prevent this or why it might happen? If I go to task manager and stop/kill all the nodejs processes they are recreated and work again.

Sounds like a missing cleanup call somewhere. If you can get me an accurate repro for what's needed to hang the process (and stop it from being cleaned up), I could look into making that path a bit more reliable

Will do. I will try to reproduce and make a new issue if so. Thank you!!
