round(): Argument #1 ($num) must be of type int|float, string given error when switching to PHP 8

[tyssen]

Description

The following code works fine if I'm using PHP 7.4, but if I change it to 8, I get

round(): Argument #1 ($num) must be of type int|float, string given

{% set thumbTransform = {
    mode: 'fit',
    height: height | default,
    width: width | default,
    quality: quality | default('90')
}%}

{{ entry.entryImage.one().url(thumbTransform) }}

If I comment out {{ entry.entryImage.one().url(thumbTransform) }}, the error goes away.

Additional info

• Craft version: 3.6.16
• PHP version: 8
• Database driver & version: MySQL 5.7.28

Looking at the stack trace, it would imply that you're passing an empty string as the width for the Asset.

Granted, Craft should be normalizing that to a 0.00 value, but thought you should be aware of it.

Thanks. Changing it to width: width | default(0) fixed it.

No problem - I made it more defensive on our end, too!
