amplify

start here: https://docs.amplify.aws/flutter/start/quickstart/

the docs say this is a pre-requisite: https://docs.amplify.aws/flutter/start/account-setup/

sudo pacman -S aws-cli-v2
aws configure sso

I followed this guide (https://docs.amplify.aws/flutter/start/account-setup/) up to step 6, at which point I got this error:

$ npx ampx sandbox
npm error could not determine executable to run

I realized this is because I was running the command outside of an amplify project. So I went back to the original guide https://docs.amplify.aws/flutter/start/quickstart/ and made the flutter project.

flutter create my_amplify_app
cd my_amplify_app
npm create amplify@latest -y

Now run:

npx ampx sandbox --outputs-format dart --outputs-out-dir lib

Runnin the above command for the first time result in the error:

[InvalidCredentialError] Failed to load default AWS credentials
  ∟ Caused by: [CredentialsProviderError] Token is expired. To refresh this SSO session run 'aws sso login' with the corresponding profile.
Resolution: To configure a new Amplify profile, use npx ampx configure profile.

So i logged in with:

aws sso login

Tried running `` again, but then get the error:

npx ampx sandbox --outputs-format dart --outputs-out-dir lib
10:56:33 AM The region ap-south-1 has not been bootstrapped. Sign in to the AWS console as a Root user or Admin to complete the bootstrap process, then restart the sandbox.
10:56:33 AM If this is not the region you are expecting to bootstrap, check for any AWS environment variables that may be set in your shell or use --profile <profile-name> to specify a profile with the correct region.

Completed the 'bootstrap' process as per the instructions and ran npx ampx sandbox --outputs-format dart --outputs-out-dir lib↲ again.

That took a while and held up the terminal like this:

$ npx ampx sandbox --outputs-format dart --outputs-out-dir lib
10:56:33 AM The region ap-south-1 has not been bootstrapped. Sign in to the AWS console as a Root user or Admin to complete the bootstrap process, then restart the sandbox.
10:56:33 AM If this is not the region you are expecting to bootstrap, check for any AWS environment variables that may be set in your shell or use --profile <profile-name> to specify a profile with the correct region.
