I can't get my escape characters correct for an AWS SSM command with double quotes inside. Here's the last attempt:

aws ssm send-command --instance-ids "i-012345678" --document-name "AWS-RunShellScript" --query "Command.CommandId"  --output text --parameters commands='["sudo su","cd /opt/cassandra/bin","cqlsh -e \"select * from system_schema.keyspaces;"\"]'

Essentially it's the last command, the double quotes around the cqlsh command that I can't escape from erroring. Have tried to store it in variable and echo but neither works. Also looked at answers below.

Per the documentation,

You do not need to escape double quotation marks embedded in the JSON string, as they are being treated literally.

Could you instead try the below?

aws ssm send-command \
--instance-ids "i-012345678" \
--document-name "AWS-RunShellScript" \
--query "Command.CommandId" \
--output text \
--parameters commands='[{"sudo su","/opt/cassandra/bin/cqlsh -e \"SELECT * FROM system_schema.keyspaces;\""}]'
