Global variables appearing as "blank" when calling a Power Automate flow

I noticed that parameters that I'm populating with global variables are displaying as "blank".

The only reason that I took notice is that in one environment the flow is running and in another it isn't. When comparing them, I saw that the variables are blank in both.

So, in the code below the gblCaseNumber and gblStudentID variables are displaying as blank. It's clearly not affecting anything in our development side, but I wasn't sure if that was normal behavior or not.

Set(
    varViewSpinner,
    true
);
UpdateContext({locSpinnerMessage:  "Printing page.  Please wait."});
UpdateContext({locPrintInfo:  GetreferralformdataintoHTML.Run(gblCaseNumber, gblStudentID,User().Email)});
Notify("Your requested report will be sent via email link", NotificationType.Information);
Set(
    varViewSpinner,
    false
);

Global variables appearing as "blank" when calling a Power Automate flow

I'm assuming gblCaseNumber and gblStudentID these are either integer or string variables?

Are you positive they're being set before the code you posted is run?

You could try adding a conditional to your code to warn you if either of the variables is blank. You could also modify this to let you know if they don't have enough character length with a len function, or add more conditions to let you know which one is blank, etc.

If(
IsBlank(gblCaseNumber) Or IsBlank(gblStudentID),
Notify("ALERT! gblCaseNumber or gblStudentID is blank!",NotificationType.Warning,2000),

//your existing code here

UpdateContext({locSpinnerMessage: "Printing page. Please wait."});

UpdateContext({locPrintInfo: GetreferralformdataintoHTML.Run(gblCaseNumber, gblStudentID,User().Email)});

Notify("Your requested report will be sent via email link", NotificationType.Information)
