I am trying to delete an item in a dynamodb table. Even if I provide the correct id, the command rejects it:

aws dynamodb delete-item --table-name my-table --key 9cjmB5rjbqYWJ6USMf9OEV13Kyoxs6VAN8xl9Sutzdl7gTpaxX2UgA==

Here’s the error I get:

Error parsing parameter '--key': Expected: ',', received: '=' for input:
9cjmB5rjbqYWJ6USMf9OEV13Kyoxs6VAN8xl9Sutzdl7gTpaxX2UgA==

Adding double quotes around the key does not work. Backslashes before ‘=’ does not do it either.
