aws ssm register-task-with-maintenance-window reports error as Invalid JSON?

Question

I am running the below command and it is reporting an error like Invalid JSON:

AWS SSM Command:

 aws ssm register-task-with-maintenance-window --window-id mw-06344a0189162e0b3 --targets Key=WindowTargetIds,Values=ae5c621a-17d8-454f-977f-46298f1e6eb8 --task-arn AWS-RunPatchBaseline --service-role-arn arn:aws:iam::xxxxxxxxxxxxx:role/AmazonSSMRoleForInstancesQuickSetup --task-type RUN_COMMAND --max-concurrency 2 --max-errors 1 --priority 1 --task-invocation-parameters '{\"Operation\":{\"Values\":[\"Install\"]}}'

Error:

Error parsing parameter '--task-invocation-parameters': Invalid JSON: Expecting property name enclosed in double quotes: line 1 column 2 (char 1)
JSON received: {\"Operation\":{\"Values\":[\"Install\"]}}

I'm using the AWS Documentation.

I used double quotes instead of the single quote but still no charm.

Finally, created an issue on GitHub for AWS Docs.

Kindly assist if you have come across an issue like this before.

The error is saying it wants "double quotes" but your example has single quotes. Maybe the docs have been updated since your posting, but it currently recommends the following format.

Linux/Windows:

--task-invocation-parameters "RunCommand={Parameters={Operation=Install}}"
