I am attempting to use the example script "ExampleTextToSpeech" that comes with the Watson Unity SDK. However, the Watson Text to Speech example throws error when attempting to synthesize. My service IAM Key appears to be correct. I am not specifying the AIM URL or the Service Url. I assume the default values should be correct since I am in the North American Region and this has worked for both the Watson Assistant and Speech to Text. The problem appears to be with the Synthesize call. I've listed the errors below.
Sorry I failed to post the actual code the first time. I assumed I didn't need to since it is the same code from the SDK demos. Please find the code below. I have removed some extraneous code bits such as customizing words from the code. The errors can be found at the end of the code block.
