Error starting up pyls over tramp: No buffer named *pyls-remote* #1580

Open rlivings39 opened 4 years ago

rlivings39 commented 4 years ago

Describe the bug Launching pyls via tramp gives error:

Error: (error "No buffer named *pyls-remote*")
tramp-file-name-handler: No buffer named *pyls-remote*

To Reproduce Start emacs with:

emacs -Q -l ~/lsp-start-plain.el

Then register a remote pyls:

(require 'lsp-mode)
(lsp-register-client
 (make-lsp-client :new-connection (lsp-tramp-connection "pyls")
                  :major-modes '(python-mode)
                  :remote? t
                  :server-id 'pyls-remote))

Then open a remote python file, start lsp, and notice error. If I create that buffer C-x b *pyls-remote* <RET> and then run M-x lsp everything launches correctly.

Can you provide the corresponding call stack (after M-x toggle-debug-on-error)?

Edit: Ignore, missed

Debug on error doesn't catch anything.
