Hi @cruelsmith ,

I tried your hotfix and the exec is applied at every puppet run. I don't have idempotency.

Notice: /Stage[main]/Wazuh::Filebeat_oss/File[/etc/filebeat/wazuh-template.json]/ensure: defined content as '{mtime}2022-09-02 14:42:47 +0000'
In the next Puppet run :
Notice: /Stage[main]/Wazuh::Filebeat_oss/File[/etc/filebeat/wazuh-template.json]/ensure: defined content as '{mtime}2022-09-02 14:47:05 +0000'

It seems that as the onlif is true, the unless is not evaluated.

Do you experience the same behaviour ?

🙈 thanks for the hint @poloz-lab

Note for myself: Trust only tests you did yourself and always ensure you using the right shell when testing the command on the shell.

To make it short the exec from #516 had never worked it always had raised a syntax error and even not it had raised a path missing for command curl. 🤦(to myself)

Now it is really tested. Working in the states if file is missing, file differ from upstream via curl and file is equal with upstream with curl. The exec to remove the file only runs when the file differ and setting the content with the mtime will only be set when file was missing.
