[Problem:]

Disclaimer - I am not positive when this error was present but I believe it may be due to 25.1 as I last updated a setting in haproxy about 2 months ago and I just updated opnsense to 25.1 about a week ago.

Version: 25.1.1

Problem: when going into haproxy to make changes, there is now a warning that reads as follows.  The service starts fine but I can't make any changes and apply it.

There are pending configuration changes that must be applied in order for them to take effect. To review them visit the Config Diff page.

• Click Test Syntax:

[NOTICE] (60298) : haproxy version is 3.0.8-6036c31
[NOTICE] (60298) : path to executable is /usr/local/sbin/haproxy
[ALERT] (60298) : config : parsing [/usr/local/etc/haproxy.conf.staging:343]: Missing LF on last line, file might have been truncated at position 1.
[ALERT] (60298) : config : Error(s) found in configuration file : /usr/local/etc/haproxy.conf.staging
[ALERT] (60298) : config : Fatal errors found in configuration.

• Reverted back to a config.xml about 1 hour before I made any changes last night and the DIFF has this message.

• In haproxy.conf.staging, when I edit the file, I see this is actually at the end but those '@^' symbols may be a lock from opnsense or something.  Deleting the lines doesn't help as it is there again shortly on trying to test/apply the haproxy settings

• Things that I have tried

- rebooted the node
- stopping/restarting haproxy
- stopping haproxy and adding a new line to haproxy.conf and haproxy.conf.staging
- also tried adding via 'echo "" >> haproxy.conf.staging'

I don't see anything obscure at a glance in my haproxy section in config.xml -- any ideas about what else I could try to fix this issue?
