Ansible get_url not registering return values - syntax

Question

I am using Ansible 2.8.1 to download from Nexus.
I want to register a variable so that in subsequent tasks, I will know what file I downloaded by looking at downloaded_file.dest.
- name: Download assembly file to /my/server/location/
get_url:
url: https://nexus.mycompany.com/service/rest/v1/search/assets/download?repository=repo-snapshots&group=group&name=name&sort=version&direction=desc
validate_certs: no
dest: /my/server/location/
force: yes
register: downloaded_file
But when running ansible-playbook 2.8.1
I get
fatal: [myserver]: FAILED! => {"changed": false, "msg": "Unsupported parameters for (get_url) module: register Supported parameters include: attributes, backup, checksum, client_cert, client_key, content, delimiter, dest, directory_mode, follow, force, force_basic_auth, group, headers, http_agent, mode, owner, regexp, remote_src, selevel, serole, setype, seuser, sha256sum, src, timeout, tmp_dest, unsafe_writes, url, url_password, url_username, use_proxy, validate_certs"}
So it's considering the register as a parameter to get_url. Is my syntax correct here? How do I get the return values from the task?

Answer 1

The syntax is wrong. register is not a parameter of get_url. It's a task's level directive.
Correct
- name: Download assembly file to /my/server/location/
get_url:
url: https://nexus.mycompany.com/service/rest/v1/search/assets/download?repository=repo-snapshots&group=group&name=name&sort=version&direction=desc
validate_certs: no
dest: /my/server/location/
force: yes
register: downloaded_file
