Using vision, Ignition 8.1.47.
Have a template that has a button on it to quickly acces a window related to the data the template is showing. Been working on this project for months, and just today started getting this -

The script that is being called
def openPump(event):
"""
Pump icon acts as a button to open the pump for that product and stall #
Args:
event: the button click
Returns:
None, opens up Pump Screen
"""
stall = event.source.parent.stall
params = {"stall":stall}
if stall == 1:
window = system.nav.openWindow('O2PumpS1', params)
system.nav.centerWindow(window)
else:
window = system.nav.openWindow('N2PumpS2', params)
system.nav.centerWindow(window)
I have another location in the project with a button that calls also tries to open this window via
def openN2Pump(stall):
window = system.nav.openWindow("N2PumpS2", {"stall":stall})
system.nav.centerWindow(window)
called like
PrivilegedAccess.nav.openN2Pump(2)
And I get the same error leading me to believe it’s soemtihng with the window itself.
I am able to open the window in designer fine. I tried opening, saving the window with a tiny change, closed and re-opened the client, and still got the same issue.
Any ideas here? Is this window bonked and I need to import from a backup?
