unity – Argument out of Vary Exception on click on of button that calls a operate that does not use an index

At the moment writing a script that builds a HUD for testing some features in a mission. It mechanically builds buttons, one in all which works, whereas the opposite provides the error indicated within the title and error message under.

The operate the button is looking works when known as by a button manually positioned within the scene, indicating that the problem is not with the operate itself however the way in which the button is being constructed.

The script compiles profitable and are rendered accurately within the edtior. Clicking the radio button (which builds the button that’s giving the error) works accurately, constructing the button and working the debug logs.

The error happens when clicking on the “subsequent music” button, which is generated by clicking on the radio button.

Right here is the error:

ArgumentOutOfRangeException: Index was out of vary. Should be non-negative and fewer than the scale of the gathering.
