UnrecognizedClientException: The security token included in the request is invalid.

I use your application as in the description, but I see the error:

Could you explain why it happens? The configuration file contains the same settings as my mobile application.

I think it's the problem about your 'region'. You may find your right region of your relevant service in this website: http://docs.amazonaws.cn/en_us/general/latest/gr/rande.html#cnnorth_region

[Aditya27]

Try specifying the region explicitly
node dynamoDBtoCSV.js -t 'tableName' --region 'us-west-2' > output.csv

In case anyone is trying this with STS, you'll need to include the sessionToken provided by STS. You can update your config.json with the "sessionToken": "REPLACEWITIHSESSIONTOKEN" value.

{
    "accessKeyId": "REPLACE",
    "secretAccessKey": "REPLACE",
    "sessionToken": "REPLACEWITIHSESSIONTOKEN",
    "region": "REPLACE"
}
