here is my config:

model = "codex-mini"
model_provider = "azure"
approval_policy = "untrusted"

[model_providers.azure]
name = "Azure"
base_url = "https://xxxxxxxxxxxx.cognitiveservices.azure.com/openai"
env_key = "AZURE_OPENAI_API_KEY"
wire_api = "responses"
query_params = { api-version = "2025-04-01-preview" }

why am i getting:

BackgroundEvent(BackgroundEventEvent { message: "stream error: unexpected status 404 Not Found: {\"error\":{\"code\":\"404\",\"message\": \"Resource not found\"}}; retrying 1/10 in 200ms…" })

@ckr0 Try to downgrade to 0.10, there's an issue with 0.11.0: https://github.com/openai/codex/issues/1796

Bug still exists in 0.12.0, everything was good with 0.10.0
