Partial Translation Request Fail: at least one translation failed, it was either invalid or more likely- rejected by the server. You can try the request again and if it persists try a proxy, spacing out requests, and/or using a different tld. If you would like to translate other requests in a batch translation even if one fails(the failed translation will be set to `null`) pass the option `rejectOnPartialFail: false`. You can also try using the singleTranslate endpoint with: `forceBatch: false`
