models file does not exist for supplier:

Error message

models file does not exist for supplier: 

What it means

SetModelTitle requires the supplier's models.json to exist, since it edits entries in that file. If SUPPLIER_CONFIG_PATH/<supplierName>/models.json is missing, it aborts with this error naming the supplier.

Solutions

1. Call GetModelList / the supplier's model-fetch routine to create models.json before editing titles
2. Verify the supplierName is correct and its config directory contains models.json
3. If the models file was deleted, re-fetch models from the supplier API to regenerate it

Example fix

// before
err := SetModelTitle("mycust", "gpt-4o", "My GPT") // no models.json yet

// after
if !public.FileExists(SUPPLIER_CONFIG_PATH + "/mycust/models.json") {
    RefreshModelList("mycust") // create models.json first
}
err := SetModelTitle("mycust", "gpt-4o", "My GPT")

modelsFile := SUPPLIER_CONFIG_PATH + "/" + supplierName + "/models.json"
if !public.FileExists(modelsFile) {
    return errors.New("run model list sync for " + supplierName + " first")
}
return SetModelTitle(supplierName, modelId, title)

if err := SetModelTitle(supplier, id, title); err != nil {
    if strings.Contains(err.Error(), "models file does not exist") {
        // trigger model-list refresh then retry once
    } else { return err }
}

When it happens

Trigger: Calling SetModelTitle for a supplier whose config directory exists but has no models.json — e.g. a freshly created supplier whose model list was never fetched/saved.

Common situations: Calling model-update APIs before the model list has been initialized; supplier name typo pointing at a non-existent/empty config dir; models.json deleted manually or lost during a failed sync.
