update-lambda-revision-id.ts

// Workaround when you change Environment Vars on Lambda functions and need to use ASK - CLI to Deploy an Skill.
// That code updates the variables through the AWS console and manually fetch the function's info using the AWS CLI and
// update the local revision id to match the revision id that's live on AWS.

// Gist link: https://gist.github.com/isaacpalomero/84de0412d3de5b3f5c0e2e4a141a0fae
// How to use it:
// npm install -g "fs"
// npm install -g "execa"
// [root-project-path]$ ts-node scripts/update-lambda-revision-id.ts

// TODO: update this values with yours
const awsCli_ProfileName = "YOUR-AWS-CLI-PROFILE"; // Download Lambda purpose
const askCli_ProfileName = "YOUR-ASK-CLI-PROFILE"; // Update .ask/config file purpose
// END-TODO
