What's Wrong?
Unsupported content type: redacted_thinking
When I use the plugin in VSCode to invoke Claude Code, there is a high probability that the final output will show "Unsupported content type: redacted_thinking".
What Should Happen?
It should display the output normally.

same problem，，，
If you're using OpenRouter, try this proxy: https://github.com/ahaostudy/openrouter-proxy
Same here
Disable /thinking may help. Might be related to 3-party providers, e.g., openrouter
I am encountering the same issue when using the VS Code claude-code extension + OpenRouter.
Disabling thinking altogether helps. Also speeds up the processing 500% in my case! Testing the proxy now.
The answer will occur if you close vscode and open it again.
same problem T_T
After two days I do not miss thinking feature. Totally redundant and wasteful (in my case at least).
same problem
It works
how to disable /thinking in vscode?
same here when using openrouter models. reopening vscode will show the answers but not during the prompt return. it works fine using claude code in the terminal but it's the vscode panel that has problems.
redacted_thinking itself is a legitimate Anthropic-style content block. It is used when thinking content is encrypted/redacted and may appear before normal text blocks. The bug is that the VS Code panel appears to get stuck or fail to render/update properly when it sees that block, even though the normal text response exists.

I am also facing same issue:
Error : Unsupported content type: redacted_thinking
VS Code + Claude code extension + OpenRouter
/Thinking is off, still same issue
I used Claude Code with OpenRouter directly on terminal without any issue.
Yes, @ankranidiotis, it only happens with the VS Code plugin, not the CLI tool
Same issue here — it only happens with the VSCode plugin.
When Claude clicks the "Chats History" button in the chat panel, the messages start to appear.
This is happening with Claude Code (Pro) on VS Code (Positron, Linux) as well.
Same issue on VS code plugin.
Same issue
VSCode plugin
Same issue, only in VSCode plugin
same issue
even after disabling thinking
+1
same
Yeah, I'm seeing this too. Looks like a bug exclusive to OpenRouter and the VS Code Claude Code extension, probably triggered by the hidden reasoning process.
Still have the issue using VS code + Claude code extension + openrouter.
disable the thinking more does not fix the issue.
I tested the openrouter-proxy shared earlier and did not fix the issue either.
I have to switch using the terminal that until a viable solution found
Same issue using VS Code 1.21.0, Claude Code for VS Code extension 2.1.198 and openrouter.ai setting all models in settings to "openrouter/auto"
