Hashicorp exclusion syntax

I’m using the latest version of hashicorp enterprise (v1.19.x) and I am trying to use the audit log exclusion syntax listed in the link below. There are examples of the syntax but not the examples within a command. I currently have used it in the following command but it’s not excluding the batch_input field from the audit log.

vault audit enable file file_path=/vault/vault_audit.log mode=0640 exclude=‘[{“fields”: [“/request/data/batch_input”]}]’

Any advice?
