invalid region

Error message

invalid region: %s

What it means

NewSmartApiClient (or the region resolution helper in smart_api.go) iterates the known region list looking for one matching the supplied baseUrl; if none matches it returns this error with the offending URL. It means the configured base URL is not one of the recognized Tuya data-center endpoints, so no client can be constructed.

Solutions

1. Use one of the library's exported/known region base URLs verbatim (e.g. openapi.tuya-XX.com)
2. Verify the exact spelling and scheme (https://) of baseUrl against the region list in smart_api.go
3. Upgrade the library if your Tuya data center is newer than the built-in region table
4. Add/patch the region entry locally if you must use a custom endpoint

Example fix

// before
client, err := tuya.NewSmartApiClient("openapi.tuya.example.com", accessID, secret)
// after
client, err := tuya.NewSmartApiClient("https://openapi.tuya-us.com", accessID, secret)
if err != nil { return fmt.Errorf("region config wrong: %w", err) }

var knownRegions = []string{"https://openapi.tuya-us.com","https://openapi.tuya-eu.com","https://openapi.tuya-china.com","https://openapi.tuya-in.com"}
func validRegion(u string) bool { return slices.Contains(knownRegions, u) }

func isKnownTuyaRegion(baseUrl string) bool {
    return strings.HasPrefix(baseUrl, "https://openapi.tuya-")
}

client, err := tuya.NewSmartApiClient(baseUrl, id, secret)
if err != nil {
    if strings.Contains(err.Error(), "invalid region") { return fmt.Errorf("bad region URL %q: %w", baseUrl, err) }
    return err
}

When it happens

Trigger: Passing a baseUrl to the Tuya smart API client factory that isn't in the library's region table — typos, custom/proxy URLs, missing scheme, or newly added Tuya regions not present in this library version.

Common situations: Copying a base URL from docs of a different SDK version, using an EU/India endpoint the library doesn't know, or trimming the scheme (https://) so the comparison fails.
