Error: LANGDOCK + Claude Sonnet 4.6 - Error 400

EDIT

I figured out when the error message appears:

When you use the ( 1 ) Text-Field it works.
When you use ( 2 ) Text-Field it shows the error message.

This is my config:

name: Local Config
version: 1.0.0
schema: v1
models:
  - name: "CODE A (Fast): Claude Sonnet 4.6"
    provider: anthropic
    model: claude-sonnet-4-6-default
    apiKey: sk-XXX
    apiBase: https://api.langdock.com/anthropic/eu/v1

Any Ideas?

Thanks for the report!

I figured out that Langdock isn't using the newest "call".
I forwarded it to Langdock and they answered:

We can confirm the point regarding “Continue”: Our OpenAI-compatible gateway currently offers external endpoints in the style of “Chat Completions” (“/v1/chat/completions”). A “/v1/responses” endpoint is not currently part of the public API.

I have noted your suggestion regarding support for “/v1/responses” and have forwarded it internally to our engineering team.

Today I tried it again (VSCode + Continue + Langdock) and it works!
So not sure if Langdock already changed something or if it was from the Plugins side (Continue).
