Aws-sam-cli: sam deploy --guided disregards region input

Created on 2 Dec 2020  路  6Comments  路  Source: aws/aws-sam-cli

Description:

after execution of sam deploy --guided it asked me about the region to deploy lambda function to. I entered "us-east-2". A few steps later it printed out a huge python stack trace with message "You must specify region".

It affects customer experience as the tool disregards information entered by a user - which does not look holistic.

Steps to reproduce:

  • Run aws configure. Enter credentials. Do not put region information.
  • Create a sample python lambda function from "Hello word" template using sam init
  • Try to deploy it with sam deploy --guided. It will ask for a region. Enter "us-east-2"
  • Follow further on-screen instructions

Observed result:

% sam deploy --guided

Configuring SAM deploy
======================

    Looking for config file [samconfig.toml] :  Not found

    Setting default arguments for 'sam deploy'
    =========================================
    Stack Name [sam-app]: 
    AWS Region [us-east-1]: us-east-2
    #Shows you resources changes to be deployed and require a 'Y' to initiate deploy
    Confirm changes before deploy [y/N]: y
    #SAM needs permission to be able to create roles to connect to the resources in your template
    Allow SAM CLI IAM role creation [Y/n]: y
    HelloWorldFunction may not have authorization defined, Is this okay? [y/N]: y
    Save arguments to configuration file [Y/n]: y
    SAM configuration file [samconfig.toml]: 
    SAM configuration environment [default]: 

    Looking for resources needed for deployment: Not found.
    Creating the required resources...
    Successfully created!

        Managed S3 bucket: aws-sam-cli-managed-default-samclisourcebucket-1lljvk7s3ie0m
        A different default S3 bucket can be set in samconfig.toml

    Saved arguments to config file
    Running 'sam deploy' for future deployments will use the parameters saved above.
    The above parameters can be changed by modifying samconfig.toml

We have found the root cause for this issue and are working on fixing it. Meanwhile, try setting the environment variable AWS_DEFAULT_REGION and see if that fixes it.

I was unable to reproduce this. When you do aws configure, does it not default to some region even if left blank?

prenx4x picture prenx4x on 3 Dec 2020

I have just tried and it is reproduced easily. Try removing your ~/.aws folder beforehand
aws configure has not any default value for a region

% aws configure
AWS Access Key ID [None]: key_id
AWS Secret Access Key [None]: secret_key_id
Default region name [None]: 
Default output format [None]:

So I deleted the ~/.aws dir, and followed the steps but it deployed successfully. I tried this in 1.12.0 and 1.13.1 both. Also default region name was none in aws configure.

let me know if you want me to collect any logs to facilitate investigation
