Describe the bug

ansible-collection-elasticstack/roles/beats/tasks/metricbeat.yml

Line 5 in 87a7dc6

beats_metricbeat_package: >

beats_metricbeat_package is being constructed with a newline character at the end (\n), which is causing a JSON parsing error. in the Install Metricbeat - * tasks.

This is happening because of the > YAML folded scalar operator used in the set_fact task.

We can manage it with the YAML scalar operator by using >- instead of >.
The minus sign tells YAML to strip the trailing newline.

- name: Construct exact name of Metricbeat package
  ansible.builtin.set_fact:
    beats_metricbeat_package: >-
      {{
      'metricbeat' +
      (elasticstack_versionseparator +
      elasticstack_version |
      string if elasticstack_version is defined else '') |
      replace(' ', '')
      }}

Great find! I'll look into it and I'll see if there's something similar elsewhere in the code. Then I'll try to provide a fix.

I can't reproduce the error. Ok, I tried it with Ubuntu 24.04 but Metricbeat installed without problems with the options you've given.

Because it's a simple fix, I'll provide a PR but we have to test a bit more before we can merge it.
