I have a saved template function, transform_awards(). However, the following template code gives an error when trying to set it for the Collections template in the Collections, covers & uploads tab:

program: transform_awards()

This used to work with the KoboTouchExtended driver, but now when I try to click OK to persist my changes in the KoboTouch configuration, I get:

calibre, version 8.7.0
ERROR: Invalid template for Collections template:: <p>The template "program: transform_awards()" is invalid:<br>Interpreter: Internal error evaluating an expression: 'list index out of range' - line number 1

However, as you can see from the template tester, it should work fine:



The code for my template function:

def evaluate(self, formatter, kwargs, metadata, _locals):
    awards = metadata.get('#awards')
    if not awards:
        return ''

    transformed_awards = []
    for award in awards:
        # Split the award record into its components
        components = award.split('.')

        # Extract the name of the award and the category
        award_name = components[0]
        award_name = award_name.removesuffix(' Award').removesuffix(' Awards')
        category_name = components[1]
        category_name = category_name.removeprefix('Best ')

        # Extract the year from the record and determine the decade it falls in
        year = int(components[2])
        decade = str(year // 10 * 10) + "s"

        # Extract the rank from the record and determine whether or not it is a winner
        rank = components[3]
        if rank == "winner":
            rank_message = "winners"
        else:
            rank_message = "nominees, etc."

       # Combine the components into the desired format
        transformed_awards.append(f"Awards: {award_name}, {category_name} ({rank_message})")

    return ':@:'.join(transformed_awards)

This seems like a bug, which is why I am reporting it, but if I am doing something wrong, then I appreciate any help getting me back in operation with my collections template. Thank you!
