Parameter values are not working in aws cli Cloudformation

Question

I am running my cloud-formation template by AWS CLI. It is working properly and creating stack on the AWS portal but I am facing one issue ie not able to change the default parameter values. I am passing my own parameters with CLI but only last parameter value is changing from the stack(ie 30) rest is not changing instead picking the default values from the template body. I have tried every possible thing by changing the positions of parameter but it still the same. So please let me know how will i resolve this annoying issue. This is my command:-

aws --region eu-north-1 cloudformation  create-stack --stack-name cli4  --template-body file://app_cli.json --parameters "ParameterKey"="Maxvalue","ParameterValue"="7","ParameterKey"="increment","ParameterValue"="1","ParameterKey"="incrementtime","ParameterValue"="30"

Answer 1

I was able to reproduce this CloudFormation behavior, removing the commas between the parameter pairs ( as shown here ) fixed it for me:

--parameters ParameterKey=Maxvalue,ParameterValue=7 ParameterKey=increment,ParameterValue=1 ParameterKey=incrementtime,ParameterValue=30

Answer 2

You dont need all that Double Quotes. Try

aws --region eu-north-1 cloudformation  create-stack --stack-name cli4  --template-body file://app_cli.json --parameters ParameterKey=Maxvalue,ParameterValue=7,ParameterKey=increment,ParameterValue=1,ParameterKey=incrementtime,ParameterValue=30
