Using Claude Code with Backend.AI GO

[landfill]

Hi,

I am writing to request assistance with an error I’m encountering while using the Gemini API.

I have followed the official guide to register my Gemini API Key and open the necessary ports. My current status is as follows:

in ~/.zshrc,
`export BACKEND_AI_GO_API_BASE="http://localhost:39080/anthropic"
export BACKEND_AI_GO_API_KEY=""

function glaude() {
ANTHROPIC_BASE_URL="$BACKEND_AI_GO_API_BASE" \
ANTHROPIC_AUTH_TOKEN="$BACKEND_AI_GO_API_KEY" \
ANTHROPIC_DEFAULT_OPUS_MODEL="gemini-3-pro-preview" \
ANTHROPIC_DEFAULT_SONNET_MODEL="gemini-3-flash-preview" \
ANTHROPIC_DEFAULT_HAIKU_MODEL="gemini-2.5-flash" \
claude
}`
Local Model: Currently stopped (disabled).

Data Flow Map: Shows a normal/active connection.

The issue occurs when I use the alias "glaude" that I've set up. I am receiving the following error message:

API Error: 400 {"type":"error","error":{"type":"api_error","message":"Invalid request sent to backend"}}

Could you please check if there is an error in my configuration or if I missed a specific step for the alias setup?

I look forward to your guidance. Thanks!
