Hi @kindred ferry, could you download a plugin diagnostic so we can review what might be happening? Thanks! https://docs.windsurf.com/troubleshooting/plugins-gathering-logs

[kindred ferry]

Thanks for your reply. Is it safe to share the logs here publicly, or can I send you a private message?

[undone pike]

Send it to me privately if you want

[kindred ferry]

Sorry, is there a solution to this problem?
I have already tried reinstalling the plugin, resetting the PyCharm settings, and even reinstalling the IDE completely with the removal of all configs.
Nothing helps.

Hi @kindred ferry, I’ve looked at the logs and it looks like you don’t have a model assigned, so no model will be used for autocomplete. Try switching from one model to another and clicking Apply so it refreshes and applies correctly.

Hi @undone pike , thanks, but I don't even have that setting
The plugin is currently in its latest release version 2.12.5

I just installed pre-release version 2.13.6 and this setting appeared, but when I try to manipulate the plugin settings, I get an error

hi everyone, i have a problem with the autocomplete suggestions with Windsurf in intellij!! any one can help?!

it was working 2 days ago, but i touched something!

[undone pike]

Hello @fresh verge, can you indicate the problem a bit more? Also attach your diagnosis so we can see what might be happening.

[fresh verge]

the autocomplete was working correctly 2 days ago, but now, maybe cuz i have changed somthing that i don't know, not working any more

i have tried with chat gpt but no results!

[undone pike]

Do you have the latest version of the plugin?

[fresh verge]

if i can share you my screen on live, would be better?

[fresh verge]

Windsurf, yes

Download Diagnostics

You can try changing the autocomplete mode, click apply and then set back the one you had before to see if it adjusts properly. Once you do it, try if it works.

[fresh verge]

i hav this

i have removed autocomplete and then put it again

nothing changed

[undone pike]

Can you reload the plugin from Tools > WIndsurf > Refresh Cascade?

[fresh verge]

done

nothing changed

there is somthong that block the function!

i think it has a correct configuration!

[undone pike]

I checked the diagnostics a bit more and this doesn’t look like a simple setting being turned off.

From your logs:

• Windsurf autocomplete is not disabled in settings
• your auth session is refreshing correctly
• but the language server is repeatedly throwing "unexpected supercomplete request for new supercomplete model"
• and IntelliJ is also showing an inline completion conflict with Amazon Q

So the most likely cause is a plugin conflict / broken inline completion state in IntelliJ, not that you changed one small Windsurf toggle.

Please try this exactly:

1. Disable Amazon Q completely
2. If enabled, also disable any other AI completion plugins (JetBrains AI Assistant, DeepSeek, etc.)
3. Keep only Windsurf enabled
4. Restart IntelliJ fully
5. Wait for indexing to finish
6. Test autocomplete in a simple Java file

If it still doesn’t work after that:
7. Uninstall Windsurf plugin
8. Restart IntelliJ
9. Install Windsurf again
10. Restart once more and test

If you want, after trying that, send a new diagnostics file with only Windsurf enabled and I’ll check it again.

have i exclude thees folders?

this is the message when i try to uninstall windsurf!

i have disabled all theese!

this is the new diagnostics file

[undone pike]

Thanks, this helps a lot.

I checked the new logs and there is one important update: the plugin conflict step actually worked. After restart, Amazon Q / AWS Core and the JetBrains ML completion plugins are disabled, so this is no longer just a plugin conflict issue.

However, Windsurf is still repeatedly throwing:
"unexpected supercomplete request for new supercomplete model"
even after those plugins were disabled.

Also, the Windsurf language server does start successfully, so the issue looks more like a corrupted / stuck Windsurf install or supercomplete state, not a simple settings toggle.

About the uninstall error:
the AccessDeniedException on language_server_windows_x64.exe usually means the process is still running or locked by Windows.

Please try this exactly:

1. Fully close IntelliJ
2. Open Task Manager
3. End all IntelliJ / Java / JetBrains Toolbox / language_server_windows_x64.exe processes
4. Try uninstalling Windsurf again (plugin)
5. If it still fails, reboot Windows
6. Before reopening IntelliJ, remove the plugin folder:

C:\Users\USER\AppData\Roaming\JetBrains\IdeaIC2024.3\plugins\codeium

7. Open IntelliJ again
8. Reinstall Windsurf cleanly
9. Test autocomplete in a simple file
10. If it still fails, run File > Invalidate Caches / Restart

I would not add folder exclusions yet unless reinstall still fails after a reboot.

Termina attività

[fresh verge]

for all of them?

intellij and java are dosn'e exist in the list of task manager

[undone pike]

No problem. Close all the ones you have there. It seems they got stuck or something. (Restarting your computer might be faster)

[fresh verge]

did everything

but nothing changed!!

[undone pike]

@fresh verge, the prerelease version can choose the autocomplete mode (normal autocomplete or supercompletion). Try switching to the prerelease. I’m going to report this to the team.

The team is already working on it 🙏

[fresh verge]

oke, so i have to wait?!
