Assume Role

[rashidcmb]

Can we assume role and use the same script

[MichaelDavisTSN]

Yes. I'd love to be able to use this in a lambda function.

@rashidcmb @MichaelDavisTSN do you want to submit a PR?

For those that need to get this to work with an assumed role. Just add a sessionToken to config.json and then add sessionToken: process.env.AWS_SESSION_TOKEN to the dynamoDBtoCSV.js file just after secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY.

Once you do that, it works perfectly.

A proper PR would have it look for the token and use it if it was present or handle it like it's handling MFA tokens. I might work try to submit one at some point. But wanted to get this out there in case anybody else needed to get it working with assumed role credentials.

Note: I'm not a Node JS developer.

It seems this method no longer works. I get this error:
