CLI Provision a Security Certificate - is it working

Question

When I use AWS's CLI to get a security certificate for a IoT Thing I enter:

aws iot​ describe-certificate --certificate-id myCertificateId --output text --query certificateDescription.certificatePem > cert.pem

but I get

usage: aws [options] [parameters] aws: error: argument command: Invalid choice, valid choices are: ...(something)

However, cert.pem file was created, but it's empty. Also, the certificate did show up in the AWS IoT console with the correct myCertificateId.

Did it work correctly? Is something wrong with the AWS CLI args parameter error handling?

Answer 1

There is a somewhat invisible typo in the code on the website, since there is a zero-width space in the command.

aws iot​ describe-certificate [...]

Just make sure that you delete/retype the beginning of the copy/paste command line and you'll be just fine!
