Compatibility Issue with lspsaga: Error codeaction/init.lua:265 attempt to index a nil value

[xinghe98]

Description

I'm encountering an error when using typescript-tool.nvim with lspsaga for code actions. The error message I receive is:
lspsaga error executing lua callback: codeaction/init.lua:265: attempt to index a nil value

This issue only occurs when I use typescript-tool.nvim as the LSP plugin for TypeScript. When I switch to vscode-typescript-language-server (vtsls), the error does not appear, and everything works as expected.

Steps to Reproduce

1. Install typescript-tool.nvim and lspsaga plugins.
2. Configure Neovim to use typescript-tool.nvim as the LSP for TypeScript.
3. Trigger a code action via lspsaga (e.g., select a piece of code and run Lspsaga code_action).
4. Observe the error.

Expected Behavior

Code actions should work without any errors.

Actual Behavior

When triggering a code action, the following error appears:

lspsaga error executing lua callback: codeaction/init.lua:265: attempt to index a nil value

Environment

• Neovim Version: NVIM v0.10.1
• typescript-tool.nvim Version: (latest)
• lspsaga Version: (latest)
• Operating System: Windows 11

Configuration Snippet

Here is the relevant part of my Neovim configuration:
