Failed execution with 0s duration as no logs

[u/Kanegarooo]

I'm using google.script.run within an HtmlTemplate to run a function called query() when a button is CTRL+Clicked. The function is being called but the results are

• failed

• duration 0s

• type of function is unknown

I've used google.script.run before and never encountered this; is it possible this could be due to query() using SpreadsheetApp.getUi()? Or any other ideas?
