Steps to reproduce:
- Create a script for metadata that output a multiline string (CLRF or LF does not seems to matter)
- Set it as a HostMetadataItem
- Set Agent debug to 4 (to have debug logs)
- Stop/Start the agent
- Look at the logs, you will see that the metadata are truncated at the first line, Change to remove the linebreaks, data is sent correctly.
Result:
Linebreak truncate the full output of metadata string.

Expected:
This should be managed as in Linux agent: Linebreak should not break the metadata.
