'AWSHTTPSConnection' object has no attribute 'server_hostname

[mjsobrep]

I am having problems getting the tts-ros1 code to work. I have permissions setup through the aws-cli and can do something like: aws polly synthesize-speech --output-format mp3 --voice-id Ivy --text 'hello, this is a test' test.mp3 which will work. I can also run the demo from the polly docs without any problem.

Running in kinetic, I have made my own config file to have the region as "us-east-1" and have modified the sample launch file to use the new config file.

I then run the launch file and get logging info that the synthesizer is running, polly is running, sound play is running. I send in a command using the voicer.py, I get some info about the text that was received, that it will use Polly, the request. And then the actual request which will be sent to aws:

Node: /polly_node Time: 12:14:10.334841966 (2019-05-22) Severity: Info Published Topics: /rosout

Amazon Polly Request: {'OutputFormat': 'ogg_vorbis', 'SpeechMarkTypes': [], 'VoiceId': 'Joanna', 'Text': 'hello', 'LexiconNames': [], 'SampleRate': '22050', 'TextType': 'text'}

Location: amazonpolly.py:_synthesize_speech_and_save:295

But then the request fails to return properly and I get this error:

Node: /polly_node Time: 12:14:10.472778081 (2019-05-22) Severity: Error Published Topics: /rosout

Any thoughts on what I am doing wrong?

It seems like your boto3 package may be out of date. Could you try running pip3 install -U boto3 and see if that resolves the issue.

Does the following work for you after starting the nodes?

rosservice call /polly SynthesizeSpeech 'hello polly' '' '' '' '' '' '' '' '' [] [] 0 '' '' '' '' '' '' false

Cool, that seemed to solve the problem. I did get a warning when installing that it might cause some problems with breaking compatibility with the aws-cli, but I am not having any problems.

Yes, after escaping the [ and ], the service call now works too.

Thanks for the help
