node-red dashboard UI 404 error from node-red main UI embedded link #1837

Closed dweston closed 3 months ago

Problem/Motivation

I've used node red within my HA OS environment for many years, however following the upgrade of the node-red addon to v v16.0.0 (Nov 15, 2023) with its breaking change moving the node-red addon code, config and data files out of the /config folder, now renamed /homeassistant folder, the node-red dashboard UI link button embedded in the node-red main UI page appears to still be being directed to its original (i.e. prior to v16) location http://homeassistant.local:8123/endpoint/ui, resulting in a 404 error. When node-red itself is invoked via its LH menu item it starts up correctly referencing its new location at http://homeassistant.local:8123/a0d7b954_nodered/ingress. Which suggests the issue is the dashboard UI path miss-referencing within the node-red itself.

One possible indication of the source of the problem could be the following reference warning within the node-red addon log:

(node:368) [DEP0128] DeprecationWarning: Invalid 'main' field in '/config/node_modules/node-red-dashboard/package.json' of 'none'. Please either fix that or report it to the module author
(Use `node --trace-deprecation ...` to show where the warning was created)

Expected behavior

Click the node-red dashboard UI button in node-red and the dashboard UI opens in a new adjacent tab.

Actual behavior

Clicking the node-red dashboard UI button in node-red results in a new adjacent browser tab being opened but with a '404 note found' error reported.

Steps to reproduce

Clicking the node-red dashboard button always produces the same 404 error.

Proposed changes

It is possible to access the node-red dashboard UI by inserting the node-red default port # 1880 into the URL the node-red addon invokes (e.g. http://homeassistant.local:1880/endpoint/ui), which correctly opens the dashboard UI via redirect to 'http://homeassistant.local:1880/endpoint/ui/#!/0?socketid=-jEm2bocxXsGoD4YAAAA'. However, this may not be a complete solution as re error pop-ups are showing the dashboard UI implying some other miscommunication, probably in the reverse direction from the UI page attempting to respond back to the node-red addon.

This not so much a suggested solution 'fix' as to shed some light on what might be the root cause.
