When using a custom API configuration with the DeepSeek v3 model, while standard chat functionality works successfully, an error prompt appears when attempting to use the autocomplete feature.

To reproduce

Hi all, apologies for the delay in triaging this. We'll look into it this week 👍

[yuwenlong]

@Patrick-Erichsen It's been a month. Have there been any results?

[Patrick-Erichsen]

Hey @yuwenlong thanks for the bump here, didn't get around to looking into this more. Are there any additional logs you can share from the Continue Console?

Pulling @jpoly1219 in here as well

Thank you for your patience. As a sanity check, can you check if the individual requests to the Deepseek chat and autocomplete endpoints are working? You could use a tool like curl or postman to check this. Could you also attach screenshots/details when you do so?

Also like Patrick mentioned above, additional logs from the Continue Console would be immensely helpful. For this you can Ctrl+Shift+P inside vscode, then type "continue console", and click on the item that says "Continue Console: Focus on Continue Console View".

Much appreciated 🙏
