Hey Guys,

I'm getting this error when I run npm run setup - the stack gets created but any subsequent updates won't deploy.

> aws cloudformation create-stack --stack-name $npm_package_config_cloudFormationStackName --template-body file://./cloudformation.json --capabilities CAPABILITY_IAM --parameters ParameterKey=AwsServerlessExpressS3Bucket,ParameterValue=$npm_package_config_s3BucketName --region $npm_package_config_region

Hi @gilesbutler, what's your aws cli config look like?

What happens if you add --output json to the end of the command in package.json?

Hey @brettstack

I'm testing it with updating new functions so I had to add it to the end of update-function command. That fixed the problem though and now outputs JSON with no errors thanks.

Should that be added to every aws call then?

[brettstack]

It would be better to find the root cause of the problem, likely in your aws cli config

[gilesbutler]

Spot on! Thanks @brettstack - I ran aws configure and changed Default output format: JSON to text and now it's working perfectly!

Thanks for your help 👍

@gilesbutler I had faced a similar issue changing "JSON" to "json" (lower case) after running aws configure solved the problem

[gilesbutler]

Awesome thanks @optimus-kart! Great spot 👍

@optimus-kart your answer works better for me. Both "text" and "json" solve the problem, but "json" gives nicely formatted, easily readable output.
