Node Red Server process crashes intermittently with ERR_HTTP2_SESSION_ERROR

[bwims]

Current Behavior

From time to time, my Node Red session crashes with the following:

26 Sep 16:38:46 - [red] Uncaught Exception:
26 Sep 16:38:46 - [error] Error [ERR_HTTP2_SESSION_ERROR]: Session closed with error code 6
at new NodeError (node:internal/errors:372:5)
at Http2Session.onGoawayData (node:internal/http2/core:680:21)
26 Sep 16:38:48 - [info]

Expected Behavior

Continuous running without a crash.

Steps To Reproduce

I don't know! Is there a way to get more verbose logging?

I have no idea how to debug this myself. I have looked at all the flows and nothing seems to be using HTTP at the time of crash.

Any pointers would be most appreciated!

Example flow

Hmm, we don't support HTTP2 (see #3314) - but it isn't very obvious what combination leads to this particular crash and whether its in the core or a contrib node at fault.

What nodes have you got installed? That might give us some clue as to any that could be listening for http traffic.

Thanks for responding!

I have a number of possible culprits installed, including one that calls Alexa.

Is there a way to find out which nodes are running at the time of crash? Verbose logging perhaps? Some have updates available, so I can do that at least.

Randomly I have this error:

1 Oct 09:08:31 - [red] Uncaught Exception: 1 Oct 09:08:31 - [error] Error [ERR_HTTP2_SESSION_ERROR]: Session closed with error code 6 at new NodeError (node:internal/errors:405:5) at Http2Session.onGoawayData (node:internal/http2/core:689:21)

and node red disconnects.

I think it's about applestrudel palette but I am not sure ....

Node red 3.1.0
node.js v16.20.2

What we need is a guide to debugging for non-developers. E.g. what log files, how to pinpoint which module causes a crash etc.
