What causes "Grok 模型 {alias} 不能同时替换并移除 API Key" in BigPizzaV3/CodexPlusPlus?

Set remove_api_key = false and keep api_key_update with the new key to rotate

Grok 模型不能同时替换并移除 API Key

Error message

Grok 模型 {alias} 不能同时替换并移除 API Key

What it means

A model entry may either replace the API key (api_key_update non-empty) or mark it for removal (remove_api_key = true), but not both. validate_request rejects the combination because the two operations are contradictory — there is no defined outcome for 'set this key and remove it'.

Solutions

Set remove_api_key = false and keep api_key_update with the new key to rotate
Clear api_key_update (empty string) and keep remove_api_key = true to delete the key
Reset the form state so only one of the two fields is ever populated

Example fix

// before
remove_api_key: true, api_key_update: "sk-new"
// after
remove_api_key: false, api_key_update: "sk-new"

Defensive patterns

Strategy: validation

Validate before calling

assert!(!(req.remove_api_key && !req.api_key_update.is_empty()), "cannot replace and remove the key at once");

Prevention

Make replace/remove a single mutually exclusive radio choice in the UI
Clear related fields when toggling remove_api_key
Centralize request-building so the invariant is checked in one place

When it happens

Trigger: save_grok_config_at called with input.remove_api_key == true AND input.api_key_update non-empty, typically when a UI checkbox is left checked while a new key is also typed in, or when merging request objects.

Common situations: Editing a model to rotate the key while the 'remove key' toggle from a previous edit is still on; JSON merge patches layering both fields; scripted updates that always set both fields.
