Hi Brandon,
hi all,
I have been experimenting with a script in the last couple of days and ended up with a reproducible crash of Tap Forms with one version of it, that I thought that someone might want to look into. (Disclaimer: AI helped me write the script as my capabilities in JavaScript are beginner level at best).
What I was doing: I have a script button on a custom layout that lets me pick an existing record from another form and link it via record.addRecordToField(), using Prompter.new() with a ‘popup’ parameter to show the choices. To add several linked records in one go, we wrapped that in a while loop and added a second Prompter (a simple Yes/No confirm using addParameter(message, null, “label”)) asking “add another?” after each pick.
The bug: As soon as this script has two different Prompter-based functions in it — even though the second one (the confirm) is never actually reached — the very first prompt crashes the whole app the moment I click its Continue button. It’s 100% reproducible, happens both from the live layout button and from the script editor’s own Run button, and happens regardless of which item I pick in the dropdown (including leaving it on the default first item).
If I strip the script down to a single Prompter call with no loop and no second Prompter function anywhere in the script, it works perfectly every time.
Here’s the full script that causes the crash:
async function Pick_Subtheme() {
await pickSubtheme();
}
async function pickSubtheme() {
var keepAdding = true;
while (keepAdding) {
var chosen = await promptPopup(“Add a Subtheme:”, “Pick Subtheme”, [“Episode IV – A New Hope”, “Episode VI – Return of the Jedi”, “Classic Star Wars”, “Lego Star Wars – Ultimate Collector’s Series”]);
if (!chosen) { keepAdding = false; break; }
// … link the chosen record …
keepAdding = await promptConfirm(“Add another Subtheme?”, “Add Subtheme”, “Done”);
}
}
function promptPopup(message, popupName, valuesArray) {
return new Promise(function (resolve) {
choice = undefined;
var p = Prompter.new();
p.addParameter(message, “choice”, “popup”, valuesArray, valuesArray[0]);
p.cancelButtonTitle = “Cancel”;
p.continueButtonTitle = “Add”;
p.show(popupName, function (status) {
resolve(status === true ? choice : false);
});
});
}
function promptConfirm(message, continueTitle, cancelTitle) {
return new Promise(function (resolve) {
var p = Prompter.new();
p.addParameter(message, null, “label”);
p.cancelButtonTitle = cancelTitle;
p.continueButtonTitle = continueTitle;
p.show(message, function (status) {
resolve(status === true);
});
});
}
var choice;
Pick_Subtheme();
The crash happens the moment I click “Add” on the very first popup — execution never even reaches promptConfirm.

I am using Tap Forms Pro 1.3.1 (Build 560) with macOS Tahoe 26.6.2.
I’m happy to send the full crash report if useful. Thanks for looking into it!
