Heartbeat monitor: use of heartbeat secret store

I would like to use the heartbeat secret store to specify passwords for my https request.

I tried testing this option with the username and password fields in the monitor configuration.
However the Uptime is reported as down.
Is this even possible ?

It'd be useful if you shared the commands you used to create the entries in the store, along with the config file that references the entries.

Hello @warkolm
I made a syntax error by introducing Control-M character while copying.
The issue is now resolved.
