awsmobile command does not work and hangs

[vu2sar]

Hi,

When using awsmobile configure/pull commands the command hangs up and does not execute. This is the same case for awsmobile init command as well

The entire command hangs and i am forced to exit it with Ctrl + C. I am running windows 10 and the latest version of nodejs.

P.S This occurs only on the latest version of nodejs(10.4) when i used the LTS everything was fine.

Same issue with same environment (Windows 10, NodeJS 10).
Downgrade on NodeJS 8.11.3 is a good workaround, thanks @vu2sar

@rqton Is correct I had node 10 and downgraded to lts and it worked Thanks!

Downgrading is not a good workaround, that is ridiculous, there are many features we would be giving up to downgrade node. What is the latest status on this, it has been in investigation for over 1 month?

After looking into the source code I am 100% positive that this issue is related to Inquirer.js in combination with NodeJS 10.x.x.

In file: lib\aws-operations\aws-config-manager.js

function setConfig(awsDetails, callback){
    if(!awsDetails){
        awsDetails = resolveAWSConfig(true)
    }
    
    let awsInfo = awsDetails.info
    let awsConfig = awsDetails.config

    inquirer.prompt([
        {
            type: 'input',
            name: 'accessKeyId',
            message: "accessKeyId: ",
            default: awsConfig.accessKeyId
        },
        {
            type: 'input',
            name: 'secretAccessKey',
            message: "secretAccessKey: ",
            default: awsConfig.secretAccessKey
        },
        {
            type: 'list',
            name: 'region',
            message: "region: ",
            choices: awsMobileRegions,
            default: awsConfig.region
        }
    ]).then(function (answers) {
        let awsConfigChanged = false
        if(answers.accessKeyId){
            let newKeyId = answers.accessKeyId.trim()
            if(awsConfig.accessKeyId != newKeyId){
                awsConfig.accessKeyId = newKeyId
                awsConfigChanged = true
            }
        }
        if(answers.secretAccessKey){
            let newKey = answers.secretAccessKey.trim()
            if( awsConfig.secretAccessKey != newKey){
                awsConfig.secretAccessKey = newKey
                awsConfigChanged = true
            }  
        }
        if(answers.region){
            let newRegion = answers.region.trim()
            if( awsConfig.region != newRegion){
                awsConfig.region = newRegion
                awsConfigChanged = true
            }  
        }
        if(awsConfigChanged){
            let jsonString = JSON.stringify(awsConfig)
            fs.writeFileSync(awsInfo.AWSConfigFilePath, jsonString, 'utf8')
            awsConfigInfoManager.setNoProfileSync(awsInfo)
        }

        if(callback){
            callback(awsDetails)
        }
    })
}

After the inquirer.prompt call, the next promise won't resolve itself. Hence it hangs up which is leading to invalid tokens.

Hi, this is really frustrating. For a company as large as Amazon, this should not be a problem. Has anyone looked at Megajin's analysis and developed an alternative?

[UnleashedMind]

Sorry to hear your frustration.
But it seems like the only work around right now is to downgrade to node 8.9.x when running on Windows 10.
People reported similar issues on inquirer when running on Windows 10

Had the same problem. The following command which bypasses the prompts worked for me:

awsmobile configure aws $AWS_ACCESS_KEY_ID $AWS_SECRET_ACCESS_KEY $AWS_DEFAULT_REGION

[akash-saxena150]

Had the same problem. The following command which bypasses the prompts worked for me:

awsmobile configure aws $AWS_ACCESS_KEY_ID $AWS_SECRET_ACCESS_KEY $AWS_DEFAULT_REGION

This worked for me as well. I'm running Node 10.15

I had the same problem and nothing was really working and I ended up using the git scm bash command line and running the command and was able to configure and init the whole thing hope that helps.
