Lambda Boto3 “Unknown service: 'sqs'”

I’ve just written a Python Lambda function which does some MySQL stuff and then sends a message off to SQS. This all works fine locally and the message is sent to SQS successfully.

I am creating an SQS Client like so:

sqsClient = boto3.client('sqs')

However, after deploying my packaged Lambda function to AWS and running the built-in Lambda test feature. I get the following error:

{
  "errorMessage": "Unknown service: 'sqs'. Valid service names are: ",
  "errorType": "UnknownServiceError",
  "stackTrace": [
    "  File \"/var/lang/lib/python3.7/imp.py\", line 234, in load_module\n    return load_source(name, filename, file)\n",
    "  File \"/var/lang/lib/python3.7/imp.py\", line 171, in load_source\n    module = _load(spec)\n",

    "  File \"/var/task/botocore/loaders.py\", line 378, in load_service_model\n    known_service_names=', '.join(sorted(known_services)))\n"
  ]
}

My initial thought was that maybe the Lambda version of boto3 doesn’t include SQS yet. I don’t think this is the issue though as I am deploying my own version of boto and botocore. I’ve also added the following lines in my function to ensure Lambda is using my deployed version of boto and and not it’s inbuilt version:

print("boto3 version:"+boto3.__version__)
print("botocore version:"+botocore.__version__)

Which is outputting the following versions:

boto3 version:1.9.87
botocore version:1.12.87

These are correct and the same as my local versions.

Any help would be appreciated. Thanks.

botocore.session.get_session().get_available_services()) is not outputting anything on the live Lambda.

Can you see what might be wrong with my deployment process?
