`(wrong-type-argument hash-table-p nil)` when renaming with Haskell Language Server

[dschrempf]

Thank you for the bug report

• [X] I am using the latest version of lsp-mode related packages.
• [X] I checked FAQ and Troubleshooting sections
• [ ] You may also try reproduce the issue using clean environment using the following command: M-x lsp-start-plain

Bug description

When trying to lsp-rename a symbol in Haskell (Haskell Language Server, lsp-haskell), I get the following error:

(wrong-type-argument hash-table-p nil) (see also backtrace below).

The lsp-mode logs indicate the language server is not giving a proper response. Is that so?

Steps to reproduce

See above.

Expected behavior

Symbol can be renamed.

Which Language Server did you use?

Haskell Language Server with lsp-haskell.

OS

Linux

I am getting a slightly different error message.

In my case, the stack shows one more function call (lsp--line-character-to-point(nil nil)) that results in:

wrong-type-argument number-or-marker-p nil

... instead of:

wrong-type-argument hash-table-p nil

... as reported in the original bug report.

In case that it matters: I am using emacs-lsp-booster as well.
