Updated all my packages, started dap-mode debugger and got this error. Here is backtrace:

I'm getting a similar error when trying to open the lsp-treemacs-symbols view.

Hello, thanks for this great tool! Today, I made a clean/fresh installation of emacs w/ doom emacs and updated all my packages, then I'm trying to use it for flutter development with the lsp-dart, but when I will try to execute some flutter test, I'm getting a similar error :

lsp-dart-test-tree--render: Symbol’s value as variable is void: treemacs-\'lsp-treemacs-generic-root-extension-instance

[yyoncho]

I am on it, it is regression due to breaking change in treemacs

[timlod]

Had the same error as other people above, just updated and now dap-mode gets stuck before hitting a breakpoint. Point is somehow in session view, and once I try to expand the current session with TAB I get the following error. Could this still be a problem with the newest treemacs? Installed with straight, on Emacs 28.1.

Let me know if you need a more info.

@timlod try deleting elpa dir, restarting emacs, and installing the packages again.

[axlblake]

@yyoncho getting the same error as @timlod.

[st1971]

@yyoncho getting the same error as @timlod as well, also get an "No message handler for processid" when starting debug session. this is using spacemacs on 28.1

[timlod]

Sorry for the late response. I was updating using straight, so that didn't really apply. I did try again just now on a clean Emacs install using package.el (28.2) and still get the same error.

[yyoncho]

@timlod can you test with M-x lsp-start-plain?

[st1971]

@yyoncho gave this a try myself this morning and it sort of works, do not get the "invalid-function lsp-treemacs-wcb-unless-killed" message... however it does not select a stopped thread automatically (process does stop at a break point but it is not highlighted until the thread is selected) and the thread has to be re-selected after each step over / into.

however it does not select a stopped thread automatically (process does stop at a break point but it is not highlighted until the thread is selected) and the thread has to be re-selected after each step over / into.

that might be a regression but open a separate issue for this.

[st1971]

Will do,the "invalid-funtion lsp-treemacs-wcb-unless-killed" seems to only happen when "with-expanded-depth" is passed to treemacs-initialize, if i comment this out then spacemacs behaves in the same way as it did when running through lsp-start-plain
