SUMMARY
Since the upgrade to Plasma 6.5, My python LSP server complains about Kate LSP
client not using skip_token_initialization=True.
The bug results in Kate showing LSP errors in my code that aren't errors.
STEPS TO REPRODUCE
1. Upgrade Plasma to 6.5
2. Configure Kate to use LSP server for python:
Default server settings:
"python": {
"command": ["pylsp", "--check-parent-process"],
"url": "https://github.com/python-lsp/python-lsp-server";,
"highlightingModeRegex": "^Python$"
},
3. Write python code
OBSERVED RESULT
Output tab:
[15:29:40  LSP Server Log] python@/home/martin
2025-10-30 15:29:40,423 CET - WARNING - pylsp.workspace - There was an error
while trying to initialize progress reporting.Likely progress reporting was
used in a synchronous LSP handler, which is not supported by progress reporting
yet. To prevent waiting for the timeout you can set
`skip_token_initialization=True`. Not every editor will show progress then, but
many will.
Traceback (most recent call last):
File "/usr/lib/python3/dist-packages/pylsp/workspace.py", line 261, in
_progress_begin
).result(timeout=1.0)
~~~~~~^^^^^^^^^^^^^
File "/usr/lib/python3.13/concurrent/futures/_base.py", line 458, in result
raise TimeoutError()
TimeoutError
[15:29:40  LSP Server Info] lint: mccabe
EXPECTED RESULT
A working LSP client that correctly checks my code for errors
