When replicating to remote pollers, Undefined Variable errors may be seen

[ddb4github]

Describe the bug
Undefined variable '$template_fields'.

I guess it should be $data_template_fields

For some fix-able(by me) issues, I'll summarize and log another ticket with diff

No, I believe the name is correct, the problem is that it isn't properly imitialised at the start as an array before it attempts to populate it after the !issset() check
