Unexpected op run behavior

I've found that if I wrap the same curl command in a script, then the translation works as expected. Ansible environment variables have to be https://docs.ansible.com/ansible/latest/collections/ansible/builtin/env_lookup.html instead of provided at runtime with -e unless wrapped in the same way. Attempting this without the wrapper shows that the Authorization header is empty instead of either the token or a secret reference string itself.

There appears to be a nuance between referencing the variables at the command line vs those that are referenced deeper within. However, from the op run docs:

Runs the given command in a subprocess. Environment variables of the parent process are passed down to the subprocess, with all secret references replaced with their corresponding secret value.

My expectation is that a ref at command invocation should be the same as any other ref to the same variable. Is this expected behavior?

Thank you!
