Parameter Validation Error using 'aws ec2 import-image'

Question

Objective is to pull .vmdk from S3 to EC2, but getting errors around the flag

```
--disk-containers
```

Using Ubuntu 18.04  
Linux version 4.15.0-30-generic (buildd@lgw01-amd64-060)  
pip 9.0.1 from /usr/lib/python3/dist-packages (python 3.6)

```
$ aws ec2 import-image --description TestVM --license-type BYOL --disk-containers UserBucket={"S3Bucket":"vm-test-data","S3Key":"VM-for-input.vmdk"} --dry-run

Parameter validation failed:
Invalid type for parameter DiskContainers[0].UserBucket, value: S3Bucket:vm-test-data, type: , valid types: 
Invalid type for parameter DiskContainers[1].UserBucket, value: S3Key:VM-for-input.vmdk, type: , valid types: 
```

I've also run this using a JSON file per the documentation, but that receives a strange error as well:

```
Error parsing parameter '--disk-containers': Expected: '=', received: 'EOF' for input:
container.json
```

Has anyone encountered this or can see a way around it?

Answer

Same error here, trying to convert an OVA to AMI, does anybody knows the right way to do it ?

Answer

Hi,   
  
I'd like to know if you were able to execute this command correctly, it's happening to me, so I don't really know what's the correct way to run this.   
  
I'm using the example provided in https://docs.aws.amazon.com/es_es/vm-import/latest/userguide/vmimport-image-import.html   
  
aws ec2 import-image --description "SOMETHING X" --license-type auto --disk-containers Description="BUSPDI",Format="vhdx",UserBucket={S3Bucket="migracion-dev803xx",S3Key="PDI.vhdx"} --dry-run
