 * Hi there,
 * I’m getting intermittent results. I tried enabling Polly on the post I listed
   above and it triggered the fatal error below:
 * `Fatal error: Uncaught exception 'Aws\Polly\Exception\PollyException' with message'
   Error executing "SynthesizeSpeech" on "https://polly.us-east-1.amazonaws.com/
   v1/speech"; AWS HTTP error: Client error:`POST [https://polly.us-east-1.amazonaws.com/v1/speech](https://polly.us-east-1.amazonaws.com/v1/speech)`
   resulted in a`400 Bad Request`response: {"message":"Invalid SSML request"} InvalidSsmlException(
   client): Invalid SSML request - {"message":"Invalid SSML request"}' GuzzleHttp\
   Exception\ClientException: Client error:`POST [https://polly.us-east-1.amazonaws.com/v1/speech](https://polly.us-east-1.amazonaws.com/v1/speech)`
   resulted in a`400 Bad Request`response: {"message":"Invalid SSML request"} in/
   app/public/wp-content/plugins/amazon-polly/vendor/aws/Aws/WrappedHttpHandler.
   php on line 192`
 * I’m really excited about this! 👍

 * Hi Rich!
    Thanks for the information! Really grateful for the test post! I’ve
   found the problem. The reason is ‘&’ sign in your post – if you will delete it,
   everything is working fine. We will fix the plugin in next patch, so that it 
   wouldn’t happen! Thank you!
 * Cheers,
    Tomasz
