list of errorss reported by yarn dev server

node 14, api 1.2,

I repeatedly see both errors, haven't been able to tie them to a specific operation, but they seem to occur anytime i bring up the dev server

root ERROR Child node 'open-editors:root' does not belong to this 'open-editors:root' tree.

this might explain our troubles with tree updating when an editor window is open.

root ERROR not caught: SyntaxError: JSON.parse: unexpected end of data at line 1 column 1 of the JSON data

this is an upstream bug related to how node writes to the filesystem, see eclipse-theia/theia#8384 .

part 2:

root ERROR not caught: TypeError: Failed to fetch

see #508 this sounds about fitting to the non-happening fetch for restxq endpoint

huh?

root ERROR caught: { code: 0, data: [ {} ] }

see #508 this about fits the restxq issue

Wrong commit message. My mistake. these errors still need investigating.
