I am trying to test the filter result using the ansible command in ad-hoc mode for ec2\_vpc\_subnet\_facts module. I can’t seem to get the “filters” parameter to work in the ad-hoc mode somehow. It keeps giving me back key value error or “unable to evaluate dictionary for filters” kind of error no matter how I put those things together.

Here’s is how my command looks like:

ansible localhost -i ./local -m ec2\_vpc\_subnet\_facts -a “profile=my-profile region=us-east-1 filters=”{ ‘vpc-id’: vpc-xxxxx }" -vvvv

And here’s the error message:

localhost | FAILED \>\> {  
“failed”: true,  
“msg”: “this module requires key=value arguments ([‘filters={’, ‘vpc-id:’, ‘vpc-xxxxx’, ‘}’])”  
}

I have played with many different formatting but I just can’t get it to work.
