Can not use JavaScript Library funcion in RPE template

This is a design limitation in RPE. A library script cannot use variables or data properties. If so, RPE will not use the script as library.

You should see the following message logged in console:
CRRPE3615E The script with id xx has data or variable references and cannot be used as a library.

Though you could use the library script function within try catch block, it is as good as calling a function that is not defined and hence it will be caught.

Did you check the "library script" property?

Could you try this in the text element?

try{
    displayAllTCNames()
}
catch(e){
    //catch and just suppress error
}
