Hi,

It looks to me like your script (wherever it is, on a window open, or client startup) just isn’t correct. There is no “fpmi.system.invokeAsynchronous” function, instead it’s [system.util.invokeAsynchronous](http://inductiveautomation.com/support/usermanuals/ignition/system_util_invokeasynchronous.htm) (and just for reference, for backwards compatibility, “system” could be replaced with “fpmi”).

I suspect your other system simply isn’t running this code, due to state or something. Or, if it’s a different version, I suppose the error could be handled in a different way.

Regards,

We were getting the fpmi.system.invokeAsynchronous Error when we had illegal characters (, . # - &) in our tags; removing them resolved the issue for us.
