How is assume role working in commuter?

[yummydum]

Hi, I have problem in s3 backend with assume role. Currently, I run commuter by the following command;

git clone [email protected]:nteract/commuter.git
cd commuter 
yarn
COMMUTER_S3_ENDPOINT=s3.ap-northeast-1.amazonaws.com COMMUTER_BUCKET=<my_bucket> COMMUTER_STORAGE_BACKEND=s3 yarn dev

The compile succeeds and I get

yarn run v1.21.1
$ npm run build:server
npm WARN lifecycle The node binary used for scripts is /var/folders/c0/rvxcyrm51z395rcx_lg444l00000gn/T/yarn--1578311114367-0.26080746994808/node but npm is using /usr/local/Cellar/node/13.5.0/bin/node itself. Use the `--scripts-prepend-node-path` option to include the path for the node binary npm was executed with.

My ~/.aws/config is structured as follows

[default]
source_profile = foo 
role_arn = arn:aws:iam::000000000000:role/my-role
region = ap-northeast-1
output = json

~/.aws/credentials as follows

[foo]
aws_access_key_id = XXXXXXXXXXXXXX
aws_secret_access_key = XXXXXXXXXXXX

And I can successfully run aws s3 ls. Any suggestions? Thank you for your help in advance :)

@yummydum We are facing this issue too. Did you resolve it?

I don't believe that we have explicit support for roles in the S3 provider for commuter.

Our S3 provider is located here.
